PCI（Peripheral Component Interconnect）局部總線是微型計算機中處理器、存儲器與外圍控制部件、擴展卡之間的互連接口，由于其速度快、可靠性高、成本低、兼容性好等特點，在各種計算機總線標準占有重要地位，基于PCI標準的接口設計已經成為相關項目開發中的一個重要的選擇。 目前，現場可編程門陣列FPGA（Field Programmable Gates）得到了廣泛應用。由于其具有規模大，開發過程投資小，可反復編程，且支持軟硬件協同設計等特點，因此已逐步成為復雜數字硬件電路設計的首選。 PCI接口的開發有多種方法，主要有兩種：一是使用專用接口芯片，二是使用可編程邏輯器件，如FPGA。本論文基于成本和實際需要的考慮，采用第二種方法進行設計。 本論文采用自上而下（Top-To-Down）和模塊化的設計方法，使用FPGA和硬件描述語言（VHDL和Verilog HDL）設計了一個PCI接口核，并通過自行設計的試驗板對其進行驗證。為使設計準確可靠，在具體模塊的設計中廣泛采用流水線技術和狀態機的方法。 論文最終設計完成了一個33M32位的PCI主從接口，并把它作為以NIOSⅡ為核心的SOPC片內外設，與通用計算機成功進行了通訊。 論文對PCI接口進行了功能仿真，仿真結果和PCI協議的要求一致，表明本論文設計正確。把設計下載進FPGA芯片EP2C8Q208C7之后，論文給出了使用SIGNALTAPⅡ觀察到的信號實際波形，波形顯示PCI接口能夠滿足本設計中系統的需要。本文最后還給出試驗板的具體設計步驟及驅動程序的安裝。

This document provides practical, common guidelines for incorporating PCI Express interconnect layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10- layer or more server baseboard designs. Guidelines and constraints in this document are intended for use on both baseboard and add-in card PCB designs. This includes interconnects between PCI Express devices located on the same baseboard (chip-to-chip routing) and interconnects between a PCI Express device located “down” on the baseboard and a device located “up” on an add-in card attached through a connector. This document is intended to cover all major components of the physical interconnect including design guidelines for the PCB traces, vias and AC coupling capacitors, as well as add-in card edge-finger and connector considerations. The intent of the guidelines and examples is to help ensure that good high-speed signal design practices are used and that the timing/jitter and loss/attenuation budgets can also be met from end-to-end across the PCI Express interconnect. However, while general physical guidelines and suggestions are given, they may not necessarily guarantee adequate performance of the interconnect for all layouts and implementations. Therefore, designers should consider modeling and simulation of the interconnect in order to ensure compliance to all applicable specifications. The document is composed of two main sections. The first section provides an overview of general topology and interconnect guidelines. The second section concentrates on physical layout constraints where bulleted items at the beginning of a topic highlight important constraints, while the narrative that follows offers additional insight.

針對目前使用的RS232接口數字化B超鍵盤存在PC主機啟動時不能設置BIOS，提出一種PS2鍵盤的設計方法。基于W78E052D單片機，采用8通道串行A/D轉換器設計了8個TGC電位器信息采集電路，電位器位置信息以鍵盤掃描碼序列形式發送，正交編碼器信號通過XC9536XL轉換為單片機可接收的中斷信號，軟件接收到中斷信息后等效處理成按鍵。結果表明，在滿足開機可設置BIOS同時，又可實現超聲特有功能，不需要專門設計驅動程序，接口簡單，成本低。 Abstract: Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot， this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller，designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter， potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU， software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot， ultrasound specific functionality can be achieved at the same time， it does not require specially designed driver，the interface is simple and low cost.

In this document, the term Ô60xÕ is used to denote a 32-bit microprocessor from the PowerPC architecture family that conforms to the bus interface of the PowerPC 601ª, PowerPC 603ª, or PowerPC 604 microprocessors. Note that this does not include the PowerPC 602ª microprocessor which has a multiplexed address/data bus. 60x processors implement the PowerPC architecture as it is speciÞed for 32-bit addressing, which provides 32-bit effective (logical) addresses, integer data types of 8, 16, and 32 bits,and ßoating-point data types of 32 and 64 bits (single-precision and double-precision).1.1 Overview The MPC106 provides an integrated high-bandwidth, high-performance, TTL-compatible interface between a 60x processor, a secondary (L2) cache or additional (up to four total) 60x processors, the PCI bus,and main memory. This section provides a block diagram showing the major functional units of the 106 and describes brießy how those units interact.Figure 1 shows the major functional units within the 106. Note that this is a conceptual block diagram intended to show the basic features rather than an attempt to show how these features are physically implemented on the device.
