达芬奇DAQNavi SDK软件开发包说明书
FeaturesDAQNavi/SDKSoftware Development Package for Advantech DAQ Products IntroductionDAQNavi is a comprehensive software package, for programmers to develop their application programs using Advantech DAQ boards or devices. This integrated software package includes drivers, SDK, tutorial and utility. With the user-friendly design, even the beginner can quickly get familiar with how to utilize DAQ hardware and write programs through the intuitive "Advantech Navigator" utility environment. Many example codes for different development environment dramatically decrease users’ programming time and effort. You can go to /daqnavi for more information about Advantech DAQNavi.Feature DetailsMultiple Operating System SupportDAQNavi supports many popular operating systems (OS) used in automation applications. For different OSs, API functions will be the same, so users can simply install the driver without modifying their program again when migrating between two different OSs. DAQNavi supports latest Windows system up to Windows 10. (both 32-bit and 64-bit). Besides Windows operating system, Linux is famous for its openness and flexibility. DAQNavi software package also supports Linux OS distributions including Ubuntu, Fedora, Debian and, Redhat. For other distributions, please contact Advantech local branch/support for more information..NET SupportDAQNavi offers a series of .NET Component objects, that you can benefit from platform-unified feature with the latest .NET technology. Users can simply drag and drop the .NET Components within .NET programming environment, such as Microsoft Visual C# and VB .NET. An intuitive window (called "DAQNavi Wizard") will pop-up, and user can perform all configurations by sequence. Programmers also can choose writing code manually with the .NET Component, to have a more flexible object calling. With Advantech CSCL technology, engineers can do the similar programming in Native environment such as Visual C++.LabVIEW SupportLabVIEW is one popular graphical development environment used for measurement and automation. For LabVIEW user, DAQNavi offer two options for programming: Express VI and Polymorphic VI. DAQNavi Express VI for LabVIEW helps user quickly complete his LabVIEW without extra wiring. When the user drags the Express VI on LabVIEW Block Diagram, a pop-up intuitive wizard window will appear and user can perform hardware parameter configurations. After that, the programming is done. So it is similar to the .NET control used in Microsoft Visual Studio environment, suitable for programming beginners. As for the Polymorphic VI, users can use several VIs and wiring to build more complex program.C/C++, Qt, ActiveX and Java SupportDAQNavi also offers C++ Class Library (for VC++ and Borland C++ Builder) and ActiveX (for Visual Basic, Delphi and BCB) for Native programming environment with the same calling interface as .NET Class Library. With DAQNavi Java Class Library, user can develop Java program to across different platforms (including Windows and Linux) by means of Java engine.Device SupportDAQNavi supports all Advantech PCI Express, PCI, PC-104, and PCI-104 cards, as well as all USB DAQ devices.Intuitive UtilityDAQNavi delivers one integrated easy-to-use and powerful utility, called Advantech Navigator. Within the Navigator, engineers can quickly start configuration and function testing for all Advantech DAQ devices, without any programming. Related user manuals are also displayed in the same environment. Besides, to help shorten development time, Advantech offers a series of DAQ applications examples (called "scenarios" in the Advantech Navigator). So programmers can refer to its source code and develop their application based on it, as well as the wiring information. Without a DAQ device at hand, engineers can generate a simulated device and use that device for programming and testing. Except for device testing, Navigator also offers complete documentation to describe how to use DAQNavi SDK to program in various development environments. Moreover, video tutorials for how to create applications in different development environments are available.Supports multiple operating systems including Windows (32-bit and 64-bit), LinuxSupports common-used development environment including Visual C/C++, Borland C Builder, Visual Basic .NET, Visual C#, Delphi, Java, VB, LabVIEW Supports Advantech PCI Express, PCI, PC/104, PCI-104, USB DAQ devices Integrated utility environment (Advantech Navigator) for device functionality testing without programmingAble to generate a simulator device in utility to program and run application without real hardware devicePre-defined scenario application examples with source code to shorten programming learning and development timeExpress VI and Polymorphic VIs for both beginner and advanced programming in LabVIEW environmentComprehensive documentations and tutorials for hardware specifications,wiring, example code and SDK programmingAll product specifications are subject to change without st updated: 20-Mar-2020。
TI最新达芬奇处理器DM6467 — TMDXEVM6467
TI最新达芬奇处理器DM6467 — TMDXEVM6467德州仪器(TI)最新推出了一款能够在多种应用间进行视频转码的新型达芬奇技术数字媒体处理器，这些应用包括媒体网关、多点控制设备、数字媒体适配器、视频安全监控DVR 以及IP 机顶盒等。
新型TM S320DM6467达芬奇处理器是一种基于DSP的片上系统(SoC)，特别适合实时多格式高清(HD)视频编解码，并配套了完整的开发工具及数字多媒体软件。
该芯片集成了ARM926EJ-S内核与600MHz C64x+ DSP内核，并采用了高清视频协处理器、转换引擎与目标视频端口接口，在执行高清H.264 HP@ L4(1080p 30fps、1080i 60fps、720p 6 0fps)的同步多格式编码、解码与转码方面，比前代处理器性能提升了十倍。
实时多格式高清转码技术DM6467专为应对商业及消费类电子市场的高清转码挑战而设计的，通过其多内核设计，能够实现较前代数字媒体处理器高十倍的性能。
DM6467 处理器集成了ARM与DSP内核，并采用高清视频/影像协处理器(HD-VICP)、视频数据转换引擎以及目标视频端口接口。
HD-VICP 通过面向HD 1080i H.264 high profile 转码的专用加速器，实现了超过3GHz 的DSP处理能力，同时视频数据转换引擎还能管理包括垂直下调节(downscaling)、色度采样(chroma samp ling) 以及菜单覆盖(menu overlay) 等功能在内的视频处理任务。
不到300MHz的DSP内核可用于管理多格式视频转码，并为其它应用预留了足够的空间。
DM6467 可满足媒体网关与MCU 等需要转码技术的市场要求，但其强大的灵活性与高效性对要求同时进行高清编码与解码的应用来说也非常具有吸引力，如视频语音或视频安全等对于多通道标清编码要求较高的市场。
该器件的连接外设中还包括标准PCI 总线及千兆以太网。

1 EncodeDecode Demo for the DVEVM/DVSDK 1.2 Niclas Anderberg SDO Applications ABSTRACT The DaVinci Digital Video Evaluation Module (DVEVM) comes with demonstration applications that illustrate the use of its software and hardware components. This document describes the design of the “EncodeDecode” demo application. The EncodeDecode demo uses the Codec Engine as well as video algorithms from Texas Instruments to first encode video data captured using the VPSS front end, and then decode this video data to be displayed on the VPSS back end peripheral of the DM6446.

2 EncodeDecode Demo for the DVEVM/DVSDK 1.2 1 Overview The encodedecode demo shows how to encode and decode video using algorithms and the Codec Engine from Texas Instruments on the DaVinci DM6446 DVEVM board. The video algorithm used is H.264 and is implemented using the xDM interface (see Section 4 for information reference). The H.264 encoder and decoder algorithms are packaged in a Codec Server (loopbackCombo.x64P) managed by the Codec Engine and executed on the DaVinci DSP core.
Figure 1. EncodeDecode Demo Architecture The DaVinci ARM core runs the demos on the Linux operating system, and all peripherals are controlled through Linux device drivers. The ARM displays a user interface on the OSD (On Screen Display) and takes input from a remote control that allows users to send commands through the EVM board’s IR interface. The DSP core runs the DSP/BIOS real time operating system and performs algorithm processing.
For information on how to run the encodedecode demo including documentation on the command-line parameters, see Section 4 on how to find the encodedecode.txt file. SPRAAH0A
EncodeDecode Demo for the DVEVM/DVSDK 1.2 3 2 Application Design The application consists of four separate POSIX threads (pthreads): the main thread (main.c), which eventually becomes the control thread (ctrl.c), the video thread (video.c), the capture thread, and the display thread (display.c). The video, display, and capture threads are spawned from the main thread before the main thread becomes the control thread. This means that 4 application threads are running in the demo process.
All threads except the original main/control thread are configured as preemptive and priority-based scheduled (SCHED_FIFO). The video, capture, and display threads share the highest priority, while the control thread has the lowest priority. For more on POSIX threads see Section 4.
