作為一種獨立于處理器的局部總線,PCI非常適用于網絡適配器、硬盤驅動器、全動態視頻卡、圖形卡及各類高速外設。據稱,目前有90%的Pentium處理器采用PCI做為系統總線。

PCI Express是由Intel，Dell，Compaq，IBM，Microsoft等PCI SIG聯合成立的Arapahoe Work Group共同草擬并推舉成取代PCI總線標準的下一代標準。PCI Express利用串行的連接特點能輕松將數據傳輸速度提到一個很高的頻率，達到遠遠超出PCI總線的傳輸速率。一個PCI Express連接可以被配置成x1，x2，x4，x8，x12，x16和x32的數據帶寬。x1的通道能實現單向312.5 MB／s（2.5 Gb／s）的傳輸速率。Xilinx公司的Virtex5系列FPGA芯片內嵌PCI-ExpressEndpoint Block硬核，為實現單片可配置PCI-Express總線解決方案提供了可能?！ ”疚脑谘芯縋CI-Express接口協議和PCI-Express Endpoint Block硬核的基礎上，使用Virtex5LXT50 FPGA芯片設計PCI Express接口硬件電路，實現PCI-Express數據傳輸

The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata transfer, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as Split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.

PCI-PCI 橋啟動時，一般需要從EEPROM 預讀取配置數據。更改EEPROM中的數據一般需要專用的燒結器，這給調試過程帶來不便。尤其是采用表貼封裝的EEPROM。本文以Intel 公司的Dec21554PCI-PCI 橋為例，介紹一種在線讀寫EEPROM 的方法。EEPROM選用的是ATMEL 公司生產的AT93LC66，4Kbit，按512×8bit 組織。

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.
