The system includes multiple query generation processes, a search process, and a presentation of search results that is sorted by category or type and that may be customized based on the professional discipline(or analogous personal characteristic of the user), thereby reducing the amount of time and cost required to retrieve relevant results.Keyword:Information management Retrieval system Object-Oriented1.INTRUDUCTIONThis invention relates to an information storage, searching and retrieval system that incorporates a novel organization for presentation of search results from large (gigabytes) domains of archived textual data.2.BACKGROUDN OF THE INVENTIONOn-line information retrieval systems are utilized for searching and retrieving many kinds of information. Most systems used today work in essentially the same manner; that is, users log on (through a computer terminal or personal microcomputer, and typically from a remote location), select a source of information (i.e., a particular database) which is usually something less than the complete domain, formulate a query, launch the search, and then review the search results displayed on the terminal or microcomputer, typically with documents (or summaries of documents) displayed in reverse chronological order. This process must be repeated each time another source (database) or group of sources is selected (which is frequently necessary in order to insure all relevant documents have been found).Additionally, this process places on the user the burden of organizing and assimilating the multiple results generated from the launch of the same query in each of the multiple sources (databases) that the user needs(or wants) to search. Present systems that allow searching of large domains require persons seeking information in these domains to attempt to modify their queries to reduce the search results to a size that the user can assimilate by browsing through them (thus, potentially eliminating relevant results).In many cases end users have been forced to use an intermediary (i.e., a professional searcher) because the current collections of sources are both complex and extensive, and effective search strategies often vary significantly from one source to another. Even with such guidance, potential relevant answers are missed because all potentially relevant databases or information sources are not searched on every query. Much effort has been expended on refining and improving source selection by grouping sources or database files together. Significant effort has also been expended on query formulation through the use of knowledge bases and natural language processing. However, as the groupings of sources become larger, and the responses to more comprehensive search queries become more complete, the person seeking information is often faced with the daunting task of sifting through large unorganized answer sets in an attempt to find the most relevant documents or information.3.SUMMARY OF THE INVENTIONThe invention provides an information storage, searching and retrieval system for a large domain of archived data of various types, in which the results of a search are organized into discrete types of documents and groups of document types so that users may easily identify relevant information more efficiently and more conveniently than systems currently in use. The system of the invention includes means for storing a large domain of data contained in multiple source records, at least some of the source records being comprised of individual documents of multiple document types; means for searching substantially all of the domain with a single search query to identify documents responsive to the query; and means for categorizing documents responsive to the query based on document type, including means for generating a summary of the number of documents responsive to the query which fall within various predetermined categories of document types.The query generation process may contain a knowledge base including a thesaurus that has predetermined and embedded complex search queries, or use natural language processing, or fuzzy logic, or tree structures, or hierarchical relationship or a set of commands that allow persons seeking information to formulate their queries.The search process can utilize any index and search engine techniques including Boolean, vector, and probabilistic as long as a substantial portion of the entire domain of archived textual data is searched for each query and all documents found are returned to the organizing process.The sorting/categorization process prepares the search results for presentation by assembling the various document types retrieved by the search engine and then arranging these basic document types into sometimes broader categories that are readily understood by and relevant to the user.The search results are then presented to the user and arranged by category along with an indication as to the number of relevant documents found in each category. The user may then examine search results in multiple formats, allowing the user to view as much of the document as the user deems necessary.4.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a block diagram illustrating an information retrieval system of the invention;FIG. 2 is a diagram illustrating a query formulation and search process utilizedin the invention;FIG. 3 is a diagram illustrating a sorting process for organizing and presentingsearch results.5.BEST MODE FOR CARRYING OUT THE INVENTIONAs is illustrated in the block diagram of FIG. 1 , the information retrieval system of the invention includes an input/output process ,a query generation process, a search process that involves a large domain of textual data (typically in the multiple gigabyte range), an organizing process, presentation of the information to the user, and a process to identify and characterize the types of documents contained in the large domain of data.Turning now to FIG. 2, the query generation process preferably includes a knowledge base containing a thesaurus and a note pad, and preferably utilizes embedded predefined complex Boolean strategies. Such a system allows the user to enter their description of the information needed using simple words/phrases made up of "natural" language and to rely on the system to assist in generating the full search query, which would include, e.g., synonyms and alternate phraseology. The user can then request, by a command such as "VI CO 1", to view the completedocument selected from the list, giving, in this case, complete information about the identity and credentials of the expert.FIG. 3 illustrates how five typical sources of information (i.e., source records) can be sorted into many document types and then subsequently into categories. For example, a typical trade magazine may contain several types of information such as editorials, regular columns, feature articles, news, product announcements, and a calendar of events. Thus, the trade magazine (i.e., the source record) may be sorted into these various document types, and these document types in turn may be categorized or grouped into categories contained in one or more sets of categories; each document type typically will be sorted into one category within a set of categories, but the individual categories within each set will vary from one set to another. For example, one set of categories may be established for a first characteristic type of user, and a different set of categories may be established for a second characteristic type of user. When a user corresponding to type #1 executes a search, the system automatically utilizes the categories of set #1, corresponding to that particular type of user, in organizing the results of the search for review by the user. When a user from type #2 executes a search, however, the system automatically utilizes the categories of set #2 in presenting the search results to the user.The information storage, searching and retrieval system of the invention resolves the common difficulties in typical on-line information retrieval systems that operate on large (e.g., 2 gigabytes or more) domains of textual data, query generation, source selection, and organizing search results. The information base with the thesaurus and embedded search strategies allows users to generate expert search queries in their own "natural" language. Source (i.e., database) selection is not an issue because the search engines are capable of searching substantially the entire domain on every query. Moreover, the unique presentation of search results by category set substantially reduces the time and cost of performing repetitive searches in multiple databases and therefore of efficiently retrieving relevant search results.While a preferred embodiment of the present invention has been described, it should be understood that various changes, adaptations and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims.中文译文:信息管理系统Wiliam K.Thomson U.S.A摘要:一个信息存储,查询和检索系统主要应用于大(千兆字节)的需要存档的文字领域。

管理信息系统外文翻译
英文文献翻译二〇年月日科技文章摘译Definition of a Management Information SystemThere is no consensus of the definition of the term "management information system". Some writers prefer alternative terminology such as "information processing system", "information and decision system", "organizational information system", or simply "information system" to refer to the computer-based information processing system which supports the operations, management, and decision-making functions of an organization. This text uses “MIS” because it is descriptive and generally understood; it also frequently uses “information system” instead of “MIS” to refer to an organizational information system.A definition of a management information system, as the term is generally understood, is an integrated, user-machine system for providing information to support operations, management, and decision-making functions in an organization. The system utilizes computer hardware and software; manual procedures; models for analysis planning, control and decision making; and a database. The fact that it is an integrated system does not mean that it is a single, monolithic structure; rather, it means that the parts fit into an overall design. The elements of the definition are highlighted below.1 Computer-based user-machine systemConceptually, management information can exist without computer, but it is the power of the computer which makes MIS feasible. The question is not whether computers should be used in management information system, but the extent to which information use should be computerized. The concept of a user-machine system implies that some tasks are best performed by humans, while others are best done by machine. The user of an MIS is any person responsible for entering input data, instructing the system, or utilizing the information output of the system. For many problems, the user and the computer form a combined system with results obtained through a set of interactions between the computer and the user.User-machine interaction is facilitated by operation in which the user’s input-output device (usually a visual display terminal) is connected to the computer. The computer can be a personal computer serving only one user or a large computer that serves a number of users through terminals connected by communication lines. The user input-output device permits direct input of data and immediate output of results. For instance, a person using the computer interactively in financial planning poses “what if” questions by entering input at the terminal keyboard; the results are displayed on the screen in a few second.The computer-based user-machine characteristics of an MIS affect the knowledge requirements of both system developer and system user. “computer-based” means that the designer of a management information system must have knowledge of computers and of their use in processing. The “user-machine” concept means the system designer should also understand the capabilities of humans as system components (as information processors) and the behavior of humans as users of information.Information system applications should not require users to be computer experts. However, users need to be able to specify their information requirements; some understanding of computers, the nature of information, and its use in various management function aids users in this task.2 Integrated systemManagement information system typically provides the basis for integration of organizational information processing. Individual applications within information systems are developed for and by diverse sets of users. If there are no integrating processes and mechanisms, the individual applications may be inconsistent and incompatible. Data item may be specified differently and may not be compatible across applications that use the same data. There may be redundant development of separate applications when actually a single application could serve more than one need. A user wanting to perform analysis using data from two different applications may find the task very difficult and sometimes impossible.The first step in integration of information system applications is an overall information system plan. Even though application systems areimplemented one at a time, their design can be guided by the overall plan, which determines how they fit in with other functions. In essence, the information system is designed as a planed federation of small systems.Information system integration is also achieved through standards, guidelines, and procedures set by the MIS function. The enforcement of such standards and procedures permit diverse applications to share data, meet audit and control requirements, and be shares by multiple users. For instance, an application may be developed to run on a particular small computer. Standards for integration may dictate that the equipment selected be compatible with the centralized database. The trend in information system design is toward separate application processing form the data used to support it. The separate database is the mechanism by which data items are integrated across many applications and made consistently available to a variety of users. The need for a database in MIS is discussed below.3 Need for a databaseThe term “information” and “data” are frequently used interchangeably; however, information is generally defined as data that is meaningful or useful to the recipient. Data items are therefore the raw material for producing information.The underlying concept of a database is that data needs to be managed in order to be available for processing and have appropriate quality. This data management includes both software and organization. The software to create and manage a database is a database management system.When all access to any use of database is controlled through a database management system, all applications utilizing a particular data item access the same data item which is stored in only one place. A single updating of the data item updates it for all uses. Integration through a database management system requires a central authority for the database. The data can be stored in one central computer or dispersed among several computers; the overriding requirement is that there is an organizational function to exercise control.4 Utilization of ModelsIt is usually insufficient for human recipients to receive only raw data or even summarized data. Data usually needs to be processed andpresented in such a way that the result is directed toward the decision to be made. To do this, processing of data items is based on a decision model. For example, an investment decision relative to new capital expenditures might be processed in terms of a capital expenditure decision model.Decision models can be used to support different stages in the decision-making process. “Intelligence” models can be used to search for problems and/or opportunities. Models can be used to identify and analyze possible solutions. Choice models such as optimization models maybe used to find the most desirable solutionIn other words, multiple approaches are needed to meet a variety of decision situations. The following are examples and the type of model that might be included in an MIS to aid in analysis in support of decision-making; in a comprehensive information system, the decision maker has available a set of general models that can be applied to many analysis and decision situations plus a set of very specific models for unique decisions. Similar models are available for planning and control. The set of models is the model base for the MIS.The management information system (MIS) not only supports the underlying bed administrator, moreover may support the intermediate deck personnel's control check, for high level also can provide certain information. The management information system frame by four parts: Information source, information processor, information user and information superintendent. The information source is the information production place; Information processor burden task/role and so on information transmission, processing, save; The information user is the information user, carries on the decision-making using the information; The information superintendent is responsible for the information system the design, the implementation and the safeguarding. The management information system is regarded as generally a pyramid shape the structure, divides into from the lower level handling of traffic to the operating control, the control check, the topmost story strategic planning. The most basic unit greatly processes the numerous and diverse transaction information and the state information framing by the task/role.In a word, the management information system (Management InformationSystem, MIS), is by the artificial leadership, using the computer hardware, the software, the network communicates these devices and other office equipments carries on the information the collection, the transmission, the processing, the storage, the update and the safeguarding by achieved the enterprise strategy competes superior, enhances the benefit and the efficiency target, supports the enterprise the high level decision-making, the intermediate deck check and the basic unit operation integration man-machine system. MIS is the superintendent provides the report, provides the enterprise the recent situation as well as the historic record. This system main localization is aims at in the enterprise, for control function and so on level plan, check and decision-making serves, provides the data generally by the lower level handling of traffic system. MIS will be able the actual enterprise's each kind of run situation, and using the past historical data forecast future, embarks the assistance enterprise from the enterprise overall situation angle to carry on the decision-making, used the message control enterprise the behavior, helped the enterprise to achieve its plan管理信息系统的定义对于“管理信息系统”并没有一致的定义。

外文文献资料Buses and InterfacesThe buses and interfaces are the fabric that connects the CPU to the peripherals that are part of the system. Each bus and interface has its own intricacies, and the level of support provided by Linux to the different buses and interfaces varies accordingly. The following is a rundown of the buses and interfaces found in embedded systems and a discussion of their support by Linux. Linux supports many other buses, such as SBus, NuBus, TurboChannel, and MCA, but these are workstation or server-centric.1. ISAThe Industry Standard Architecture (ISA) bus was designed for and occupied the core of PC-AT architecture. It was odd even for its time, as it did not provide many of the facilities other buses offered, including ease of mapping into normal processor physical address space. Its simplicity, however, favored the proliferation of many devices for the PC, which, in turn, favored the use of PCs in embedded applications.ISA devices are mostly accessed through the I/O port programming already available in the x86's instruction set. Therefore, the kernel does not need to do any work to enable device drivers to use the bus. Instead, the various device drivers access the appropriate I/O ports directly using the in/out assembly functions. Although the kernel provides support for Plug and Play (PNP) devices, this capability is of little use for embedded applications. Instead, embedded systems that do need to support hardware variations will be based on buses that support runtime hardware addition and removal, such as CompactPCI, PCMCIA, and USB. The kernel also supports Extended ISA (EISA) devices, but this bus has not been very popular and has been superseded by the PCI bus.2. PCIThe Peripheral Component Interconnect (PCI) bus, managed by the PCI Special Interest Group (PCI-SIG), is arguably the most popular bus currently available. Designed as a replacement for ISA, it is used in combination with many different architectures, including the PPC and the MIPS, to build different types of systems,including embedded devices.Unlike ISA, PCI requires software support to enable it to be used by device drivers. The first part of this support is required to initialize and configure the PCI devices upon bootup. On PC systems, this is traditionally done by the BIOS. However, the kernel is capable of carrying out this task itself. If the BIOS has carried out the initialization, the kernel will browse the BIOS's table to retrieve the PCI information. In both cases, the kernel provides device drivers with an API to access information regarding the devices on the PCI bus and act on these devices. There are also a number of user tools for manipulating PCI devices. In short, the level of support for PCI in Linux is fairly complete and mature.3.PCMCIAPersonal Computer Memory Card International Association (PCMCIA) is both the common name of a bus and the name of the organization that promotes and maintains related standards. Since the publication of the initial standard, which supported only 16-bit cards, other standards have been published, including the 32-bit CardBus and the USB CardBay specifications. When part of an embedded system, PCMCIA renders it flexible and easy to extend. On the iPAQ, for instance, it enables users to connect to a LAN using a wireless networking card. In other systems, it makes large permanent storage space available through the use of CompactFlash cards.The extent of Linux support for PCMCIA can be confusing. First and foremost, there is the main Linux PCMCIA project, which is hosted on SourceForge at :/// and is maintained by David Hinds. The package made available by this project supports a large number of cards, Linux support for PCMCIA is quite mature for the i386 architecture and available in part for the PPC, but unfortunately, it's still in its infancy for other chips at the time of this writing. Apart from the package maintained by Hinds, the official kernel contains support for a portion of the PCMCIA cards supported by the Hinds' package. The developers' intent is to have the official kernel become the main source for PCMCIA support. Until then, the best choice is to use Hinds' distribution for production systems. It includes the necessary system tools to configure the automatic loading and unloading of the appropriate PCMCIA device drivers when a card is inserted or removed from a PCMCIA slot.4. PC/104Although simple, the ISA bus is not well adapted to the rugged environments where embedded systems are deployed. The PC/104 form factor was introduced toaddress the shortcomings of ISA's mechanical specification. PC/104 provides a bus whose electrical signals are identical to those of the ISA bus, but with a different mechanical specification that is more adapted to embedded system development by providing ease of extensibility and ruggedness. Instead of using slots where cards are inserted, as in a regular ISA setup, PC/104 specifies the use of pin connectors. When PCI became popular, the PC/104+ specification was introduced to provide a PCI-signal-compatible bus as an addition to the PC/104 specification. Both PC/104 and PC/104+ are managed by the PC/104 Consortium, which includes more than a 100 member companies.The PC/104 is identical to ISA and the PC/104+ is identical to both ISA and PCI from the signal perspective and, therefore, from the software's perspective. Therefore, Linux requires no special functionality to support these buses. However, this does not mean that Linux supports all PC/104 and PC/104+ devices. As with any other ISA or PCI device, you should seek exact information about Linux compatibility with the PC/104 device you are evaluating.5. VMEThe VME bus is largely based on Motorola's VERSA backplane bus, which was developed specifically for the 68000 in 1979. At the time, VERSA was competing with buses such as Multibus, STD, S-100, and Q-bus, although it is rarely used today. Striving to provide a new bus that would be microprocessor independent, Motorola, Mostek, and Signetics agreed that the three companies would support a new bus. This came to be the VME bus based on the VERSA's electrical signals and the Eurocard mechanical form factor. In the Eurocard form factor, VME boards are loaded vertically into a VME chassis and connected to its backplane using pin connectors, unlike common computer boards that use edge connectors inserted into slots. Since its introduction, the VME bus has become widely adopted as the preferred bus for building powerful and rugged computers. One factor that has helped the VME bus' popularity is that it is an open standard that isn't controlled by any single organization.As the VME bus can accommodate multiple VME boards, each with its own CPU and OS, no central OS controls the bus. Instead, arbitration is used to permit a board to become bus master momentarily to conduct its operations. The job of Linux on a VME board is therefore to interact properly with its VME hardware interface to obtain the appropriate functionality.pactPCIThe CompactPCI specification was initiated by Ziatech and was developed by members of the PCI Industrial Computer Manufacturer's Group (PICMG), which oversees the specification and promotes the use of CompactPCI. The CompactPCI specification provides an open and versatile platform for high-performance, high-availability applications. Its success is largely based on the technical choices made by its designers. First, they chose to reuse the Eurocard form-factor popularized by VME. Second, they chose to make the bus PCI-compatible, hence enabling CompactPCI board manufacturers to reuse low-cost PCI chips already available in the mainstream market.Technically, the CompactPCI bus is electrically identical to the PCI bus. Instead of using slot connections, as found in most workstations and servers, pin connectors are used to connect the vertically loaded CompactPCI boards to the CompactPCI backplane, much like VME. As with PCI, CompactPCI requires a single bus master, in contrast with VME, which could tolerate multiple bus masters, as explained earlier. Consequently, CompactPCI requires the permanent presence of a board in the system slot. It is this board that arbitrates the CompactPCI backplane, just as a PCI chipset would arbitrate a PCI bus in a workstation or a server.In addition, the CompactPCI specification allows for the implementation of the Hot Swap specification, which describes methods and procedures for runtime insertion and removal of CompactPCI boards. This specification defines three levels of hot swapping. Each level implies a set of hardware and software capabilities. Here are the available levels and their requirements: Basic hot swapThis hot swap level involves console intervention by the system operator. When a new card is inserted, she must manually inform the OS to power it up and then configure and inform the software of its presence. To remove a card, she must tell the OS that the board is about to be removed. The OS must then stop the tasks that are interacting with the board and inform the board to shut down.Full hot swapIn contrast to basic hot swap, full hot swap does not require console intervention by the operator. Instead, the operator flips a microswitch attached to the card injector/ejector to notify the OS of the impending removal. The OS then performs the necessary operations to isolate the board and tell it to shut down. Finally, the OS lights an LED to notify the operator that the board can now be removed. On insertion, the OS carries out the inverse operations when it receives the appropriate insertion signal.High AvailabilityIn this level, CompactPCI boards are under complete software control. A hot swap controller software manages the state of all the boards in the system and can selectively reverse these individual boards according to the system's state. If a board fails, for example, the controller can shut it down and power up a duplicate board that is present within the same chassis for this very purpose. This hot swap level is called "High Availability," because it is mostly useful in what are known as high-availability applications,such as telecommunications, where downtime must be minimal.Linux accommodates the basic CompactPCI specification, through the PCI support it already provides. Support for dynamic insertion and removal of devices in Linux also exists in different forms. Primarily, Version 2.4 of the kernel includes the required kernel functionality.That said, this level of support is insufficient to accommodate all the complexities of CompactPCI systems. In addition, there are few drivers within the main kernel tree for mainstream CompactPCI boards, although CompactPCI board manufacturers may provide Linux drivers. This caveat has led to the emergence of a number of commercial solutions that provide high-availability Linux solutions on CompactPCI, including Availix's HA Cluster and MontaVista's High Availability Framework. The ongoing High-Availability Linux Project, found at :///, aims at providing the open source components needed to build high-availability solutions using Linux. The project isn't restricted to a specific hardware configuration and is, therefore, not centered around CompactPCI.In the future, we may see more open source software accommodating the various complexities of CompactPCI-based systems, both in terms of hot swap capabilities and in terms of software support for communication, resource monitoring, cluster management, and other software components found in high-availability systems. For now, however, if you want to use Linux for a CompactPCI-based high-availability application, you may need to work with one of the existing commercial solutions to obtain all the features described by the CompactPCI specification.7. Parallel PortAlthough not a bus in the traditional sense, the parallel port found in many computers can be used to connect a wide range of peripherals, including hard drives, scanners, and even network adapters. Linux support for parallel port devices is extensive, both in terms of the drivers found in the kernel and the ones providedby supporting projects. There is no central authority or project, however, that directs Linux's support for parallel port devices, since the parallel port is a ubiquitous component of computer systems. Instead, there are good resources that describe which devices are supported. These include the Hardware Compatibility HOWTO found at the LDP and the Linux Parallel Port Home Page found at :// /linux-pp.html. It is worth noting that Linux supports the IEEE1284 standard that defines how parallel port communication with external devices is carried out.As the parallel port can be used for many purposes besides attaching external devices, I will discuss parallel port programming when explaining the use of the parallel port as in an I/O interface in Section 3.3.8. SCSIThe Small Computer Systems Interface (SCSI) was introduced by Shugart Associates and eventually evolved into a series of standards developed and maintained by a series of standard bodies, including ANSI, ITIC, NCITS, and T10. Although mainly thought of as a high-throughput interface for hard drives for high-end workstations and servers, SCSI is a general interface that can be usedto connect various hardware peripherals. Only a small segment of embedded systems ever use SCSI devices, though. These systems are typically high-end embedded systems such as the CompactPCI-based high-availability systems discussed earlier.In those cases, a CompactPCI SCSI controller inserted in the CompactPCI backplane provides an interface to the SCSI devices.If you consider using SCSI in an embedded system, note that although Linux supports a wide range of SCSI controllers and devices, many prominent kernel developers believe that the kernel's SCSI code requires major work or even a complete rewrite. This doesn't mean that you shouldn't use SCSI devices with Linux.It is only a warning so that you plan your project's future updates in light of such possible modifications to the kernel's SCSI layer. At the time of this writing, work on the SCSI code has not yet started. It is expected that such work wouldbe undertaken during the 2.5 development series of the kernel. For now, the SCSI hardware supported by Linux can be found in the Hardware Compatibility HOWTO from the LDP. As with the parallel port, there is no single reference point containingall information regarding Linux's support for SCSI, since the SCSI interface isan established technology with a very large user base.Discussion of the kernel's SCSI device drivers architecture can be foundat :// /sg/, at :// /scsi.html, and in theLinux 2.4 SCSI subsystem HOWTO from the LDP. This should be the starting point for the development of any SCSI driver for Linux, along with the Linux Device Drivers book by O'Reilly. For a broad discussion about SCSI, The Book of SCSI: I/O For The Millennium by Gary Field and Peter Ridge (No Starch Press) is a good start. As with other standards, there are always official standards documents provided by the standard bodies, but again, such documentation often makes for dry reading material.9. USBThe Universal Serial Bus (USB) was developed and is maintained by a group of companies forming the USB Implementers Forum (USB-IF). Initially developed to replace such fragmented and slow connection interfaces as the parallel and serial ports traditionally used to connect peripherals to PCs, USB has rapidly established itself as the interface of choice for peripherals by providing inexpensive ease of use and high-speed throughput. Although mainly a mainstream device-oriented bus, USB is increasingly appearing in hardware used in embedded systems, such as SBCs and SoCs from several manufacturers.USB devices are connected in a tree-like fashion. The root is called the root hub and is usually the main board to which all USB devices and nonroot hubs are connected. The root hub is in charge of all the devices connected to it, directly or through secondary hubs. A limitation of this is that computers cannot be linked in any form of networking using direct USB cabling.There are also USB network adapters, including Ethernet adapters, that can be used to connect the computers to a common network.Support within Linux for behaving as a USB root hubis quite mature and extensive, comparing positively to the commercial OSes that support USB. Although most hardware vendors don't ship Linux drivers with their USB peripherals, many have helped Linux developers create USB drivers by providing hardware specifications. Also, as with other hardware components, many Linux drivers have been developed in spite of their manufacturers' unwillingness to provide the relevant specifications. The main component of Linux's support for USB is provided by the USB stack in the kernel. The kernel also includes drivers for the USB devices supported by Linux. User tools are also available to manage USB devices. The user tools and the complete list of supported devices is available through the Linux USB project web site at :// /.Support within Linux for behaving as a USB device is limited in comparison to its support for behaving as a USB root hub. While some systems running Linux,such as the iPAQ, can already behave as devices, there is no general agreed-upon framework yet for adding USB device capabilities to the Linux kernel.Development of USB drivers is covered by the Programming Guide for Linux USB Device Drivers by Detlef Fliegl, available through the Linux USB project web site. The Linux Device Drivers book also provides guidelines on how to write Linux USB drivers. There are a number of books that discuss USB, which you can find by looking at the various online bookstores. However, the consensus among developers and online book critics seems to indicate that the best place to start, as well as the best reference, is the original USB specification available online from the USB-IF.10. IEEE1394 (FireWire)FireWire is a trademark owned by Apple for a technology they designed in the late 80s/early 90s. They later submitted their work to the IEEE and it formed the basis of what eventually became IEEE standard 1394. Much like USB, IEEE1394 enables devices to be connected using simple and inexpensive hardware interfaces. Because of their similarities, IEEE1394 and USB are often considered together. In terms of speed, however, it is clear that IEEE1394's architecture is much more capable than USB of accommodating throughput-demanding devices, such as digital cameras and external hard drives. Recent updates to the USB standard have reduced the gap, but IEEE1394 still has a clear advantage in regards to currently existing high-throughput devices and future capabilities. Although only a small number of embedded systems actually use IEEE1394, it is likely that the need for such a technology will increase with the demand in throughput.In contrast to USB, IEEE1394 connections do not require a root node. Rather, connections can be made either in a daisy-chain fashion or using an IEEE1394 hub. Also, unlike SCSI, connections do not need any termination. It is also possible to connect two or more computers directly using an IEEE1394, which isn't possible with USB. To take advantage of this capability, there is even an RFC specifying how to implement IP over IEEE1394. This provides an inexpensive and high-speed network connection for IEEE1394-enabled computers.Linux's support for IEEE1394 isn't as extensive as that provided by some commercial OSes, but it is mature enough to enable the practical, every day use of quite a number of IEEE1394 hardware devices. The kernel sources contain the code required to support IEEE1394, but the most up-to-date code for the IEEE1394 subsystem and the relevant user utilities can be found at the IEEE1394 for Linux project web site at :// /. The list of supported devices canbe found in the compatibility section of the web site. The number and types of devices supported by Linux's IEEE1394 can only increase in the future.Support for running an IP network over IEEE1394 in Linux is currently in its infancy. In due time, this may become a very efficient way of debugging embedded Linux systems because of the quantity of data that can be exchanged between the host and the target.Documentation on how to use the IEEE1394 subsystem under Linux with supported hardware can be found on the IEEE1394 for Linux project web site. The web site also includes links to documentation regarding the various specifications surrounding IEEE1394. The main standard itself is available from the IEEE and is therefore expensive for a single individual to purchase. Although the standard will be a must for any extensive work on IEEE1394, the FireWire System Architecture book by Don Anderson (Addison Wesley) is a good place to start.11.GPIBThe General-Purpose Interface Bus (GPIB) takes its roots in HP's HP-IB bus, which was born at the end of the 1960s and is still being used in engineering and scientific applications. In the process of maturing, GPIB became the IEEE488 standard and was revised as late as 1992. Many devices that are used for data acquisition and analysis are, in fact, equipped with a GPIB interface. With the advent of mainstream hardware in this field of application, many GPIB hardware adapters have been made available for such mainstream hardware and for PCs in particular.GPIB devices are connected together using a shielded cable that may have stackable connectors at both ends. Connectors are "stackable" in the sense that a connector on one end of a cable has the appropriate hardware interface to allow for another connector to be attached to it, which itself allows another connector to be attached. If, for instance, a cable is used to connect a computer to device A, the connector attached to A can be used to attach the connector of another cable going from A to device B.12. I2CInitially introduced by Philips to enable communication between components inside TV sets, the Inter-Integrated Circuit (I2C) bus can be found in many embedded devices of all sizes and purposes. As with other similar small-scale buses such as SPI and MicroWire, I2C is a simple serial bus that enables the exchange of limited amounts of data among the IC components of an embedded system. There is a broad range of I2C -capable devices on the market, including LCD drivers, EEPROMs, DSPs, and so on. Because of its simplicity and its hardware requirements, I2C can beimplemented either in software or in hardware.Connecting devices using I2C requires only two wires, one with a clock signal, serial clock (SCL), and the other with the actual data, serial data (SDA). All devices on an I2C bus are connected using the same wire pair. The device initiating a transaction on the bus becomes the bus master and communicates with slaves using an addressing scheme. Although I2C supports multiple masters, most implementations have only one master.The main kernel tree includes support for I2C, a number of devices that use I2C, and the related System Management Bus (SMBus). Due to the heavy use of I2C by hardware monitoring sensor devices, the I2C support pages are hosted on the Linux hardware monitoring project web site at ://www2.lm-sensors.nu/~lm78/. The site includes a number of links, documentation, and the most recent I2C development code. Most importantly, it contains a list of the I2C devices supported along with the appropriate driver to use for each device.中文翻译稿应用技术学院06计算机(0616403062)管玲玲2010年2月总线和接口总线和接口是连接CPU到系统的部分外设的组织。
