主板详细讲解

主板详细讲解简介主板,又叫主机板(mainboard)、系统板(systemboard)或母板(motherboard);它安装在机箱内,是微机最基本的也是最重要的部件之一。
主板一般为矩形电路板,上面安装了组成计算机的主要电路系统,一般有BIOS芯片、I/O控制芯片、键盘和面板控制开关接口、指示灯插接件、扩充插槽、主板及插卡的直流电源供电接插件等元件。
主板的另一特点,是采用了开放式结构。
主板上大都有6-8个扩展插槽,供PC 机外围设备的控制卡(适配器)插接。
通过更换这些插卡,可以对微机的相应子系统进行局部升级,使厂家和用户在配置机型方面有更大的灵活性。
总之,主板在整个微机系统中扮演着举足轻重的角色。
可以说,主板的类型和档次决定着整个微机系统的类型和档次,主板的性能影响着整个微机系统的性能。
常见的PC机主板的分类方式有以下几种:一、按主板上使用的CPU分有:386主板、486主板、奔腾(Pentium,即586)主板、高能奔腾(Pentium Pro,即686)主板。
同一级的CPU往往也还有进一步的划分,如奔腾主板,就有是否支持多能奔腾(P55C,MMX要求主板内建双电压),是否支持Cyrix 6x86、 AMD 5k86 (都是奔腾级的CPU,要求主板有更好的散热性)等区别。
二、按主板上I/O总线的类型分•ISA(Industry Standard Architecture)工业标准体系结构总线.•EISA(Extension Industry Standard Architecture)扩展标准体系结构总线.•MCA(Micro Channel)微通道总线. 此外,为了解决CPU与高速外设之间传输速度慢的"瓶颈"问题,出现了两种局部总线,它们是:•VESA(Video Electronic Standards Association)视频电子标准协会局部总线,简称VL总线.•PCI(Peripheral Component Interconnect)外围部件互连局部总线,简称PCI总线. 486级的主板多采用VL总线,而奔腾主板多采用PCI总线。

1300 Henley CourtPullman, WA 99163509.334.6306CoolRunner-II™ Starter Board Reference ManualRevised April 8, 2016This manual applies to the CoolRunner-II rev. FOverviewThe CoolRunner-II Starter Board is a complete USB-powered circuit development platform for Xilinx's CoolRunner-II CPLD. The board includes highly-efficient power supplies, a programmable oscillator, several I/O devices, and a USB2 port for board power and CPLD programming. The board also includes five expansion connectors that make 64 CPLD signals available to external circuits.Features include:∙ A 256-macrocell CoolRunner-II CPLD in a TQ-144 package∙An on-board USB2 port for board power, JTAGprogramming, and data transfers∙An 8MHz fixed-frequency oscillator and asocket for a crystal oscillator∙Expansion connectors for 64 I/O signals (32 onthe Pmod ports and 32 on the parallelconnector)∙ a one-wire DS28E01Q EEPROMThe CoolRunner-II Starter Board.A large collection of board-support IP, reference designs, and add-on peripheral module boards (Pmods) is available at .External Power ConnectorUSBJTAG Header 1ConfigurationThe CoolRunner-II board's CPLD must be configured (or programmed) by the user before it can perform any functions. Files can be created from schematics or HDL source files using the free ISE WebPack software from Xilinx. Configuration files can be transferred to the CoolRunner-II board using a USB cable and Xilinx's iMPACT software or using an external programming cable (not included). Once configured, the CPLD retains its state indefinitely. When the CoolRunner-II board is powered on, the most recently loaded CPLD configuration is available immediately. A new configuration can be loaded at any time, and as soon as a new configuration is loaded, it defines the CPLD's behavior.2 Power SuppliesThe CoolRunner-II board can be powered from its integral USB port or from an external supply attached atconnector JP3. Jumper JP2 selects whether the board uses USB power or external power. External power, from any source, is routed through a Maxim LT3028 regulator to produce the two voltage supplies (3.3V I/O and 1.8V core) required by the CPLD. Whenever board power is applied, the power-on LED glows.To use an external power source, set jumper JP2 to BAT and apply power to the JP3 pins (see the board's silkscreen for orientation). Any 4.5V to 9V power supply can be used (for example, a transistor battery or a series arrangement of AA cells).The CoolRunner-II board uses a four-layer PCB, with the inner layers dedicated to V CC and GND. The Maxim regulators, together with good power supply routing and ample bypass capacitors on all IC pins, results in a low-noise power supply.3 ClocksThe CoolRunner-II board includes a fixed-frequency oscillator that produces an 8MHz clock signal. This primary oscillator output, labeled PCLK in the schematic, is connected to the GCLK2 pin of the CPLD (at P38) so that it can be routed to the internal clock divider. An unloaded socket for a standard half-size DIP oscillator is also provided at location IC3.4 User I/OThe CoolRunner-II board provides two pushbuttons and two slide switches for inputs, and four red LEDs and a four-digit LED display for outputs.The active-low pushbuttons and slide switches include series resistance for short-circuit protection. The LEDs are active low, and the seven-segment display uses decoupled-transistor active-high common anode signals and active-low cathodes.Three additional LEDs indicate USB power good (LD4), board power good (LD5), and USB link status (LD6).5 Expansion ConnectorsThe CoolRunner-II board provides four 12-pin peripheral module ports. Each port provides two V DD and GND connections and eight unique CPLD signals. Each port can accommodate a single 12-pin Pmod or two 6-pin Pmods.Digilent makes several 6-pin Pmods that can attach to these ports, including speaker boards, H-bridge boards, sensor boards, etc. See for more information.The CoolRunner-II board also provides a 40-pin expansion connector that includes three power-supply signals and 37 individual I/O signals.6 Demonstration DesignThe design pre-programmed onto the CPLD contains several functions that can be seen when the appropriate peripheral modules are inserted into the relevant ports.In this sample design, the switch Pmod goes in port J8, the PS/2 Pmod goes in port J7, and the seven-segment display Pmod goes in ports J5 and J6. Of course, the design can be changed to use different ports.The CPLD implements both a counter as well as a PS/2 keyboard decoder. The display switches between the two based on the value of SW4. SW1, 2, and 3 are not used in the design. BTN0 is the system reset for the design.When SW4 has the PS/2 decoder selected, the output on the display is the scan code for that letter. Here are some scan codes, the rest can be found on the Internet.7 Design Recommendations∙The regulator provides Vccio of 3.3V, so set the Default I/O Standard appropriately.∙Unused I/O should be set to Ground to minimize power.∙Input Termination should be set to Keeper to minimize power consumption on any potentially floating input pins.。

Inspect battery for rips, tears, or cuts in the housing. If there is any exposed, internal content of the battery, it could potentially affect the operation of the sight.Outer Housing CareSee the heading ‘Cleaning Instructions’ (page 12). /133 / MAINTENANCEService and Repair• Contact EOTECH’s Customer Service Department at /help-center.• B e sure to leave a name, contact number, return shipping address, and failure description in the email or on a voice mail. This will allow the manufacturer to generate a Return Authorization Number (RA#) to include with the sight(s).PRO TIP: Do not ship the sight(s) without a return authorization number — this will severely delay the turnaround time on repair or replacement.• I f required, fill out a DD Form 1149 to include with the sight(s) you will return. Include a reference to the RA#, and a signature line for EOTECH’s Service Department to sign indicating the receipt of materials. The signed copy will be mailed, faxed, or emailed back to you upon receipt of the sight(s) for the purposes of accountability.• If the manufacturing date is more than five years old, a fee will be assessed for repair to include the cost of both parts and labor. A purchase order will be required to process the repair. Please contact EOTECH for an estimate.• Please send the unit postage prepaid. Please include your name, address, telephone number, and a written description of the problem you are encountering, and also include the RA #.
