PCI(Peripheral Component Interconnect)總線以其高性能、低成本、開放性、獨立于處理器、軟件透明等眾多優點成為當今最流行的計算機局部總線。在嵌入式系統領域中,許多IP都是基于PCI總線設計的。本文闡述一種以ARM9作為CPU的嵌入式系統的PCI北橋設計與驗證。 首先介紹基于ARM的嵌入式系統結構,并深入研究PCI2.2總線行為規范。在此基礎上提出一種基于ARM處理器的PCI總線北橋的設計方案,整個設計主要分為主設備接口模塊,目標設備接口模塊,配置寄存器模塊和集成總線仲裁器三大部分。對于主設備接口模塊和目標設備接口模塊,論文主要從數據通路和控制路徑的實現兩方面進行闡述。對于集成的總線仲裁器,設計采用兩優先級的循環優先算法,通過一組設備編號寄存器實現了PCI總線上的仲裁,此外,論文對跨時鐘域的信號同步和PCI配置寄存器也作了較為詳細的描述,最終采用自頂向下的方法實現了整個設計。 在驗證部分,引入了基于平臺的驗證思路,通過搭建驗證平臺,可以高效地實現驗證。論文重點討論了驗證平臺的搭建和行為模型的建立,并介紹了一種命令總線,通過打包各個驗證點控制驗證流程。此外,為提高驗證的自動化程度,論文對驗證所使用的腳本也進行了描述。通過此驗證平臺和腳本,提高了整個驗證系統的可移植性和可重用性。 論文最終完成了PCI北橋的RTL級的功能描述,并使用仿真軟件完成對設計的仿真驗證。設計通過驗證并成功實現在基于ARM的集成處理器,達到預定的功能設計要求,并具有良好的性能,最后對后續開發進行了探討。

進入20世紀90年代后,隨著全球信息化、智能化、網絡化的發展,嵌入式系統技術獲得了前所未有的發展空間。 嵌入式系統的最大特點之_是其所具有的目的性或針對性,即每一套嵌入式系統的開發設計都有其特殊的應用場合與特定功能,這也是嵌入式系統與通剛的計算機系統最主要的區別。由于嵌入式系統是為特定的目的而設計的,且常常受到體積、成本、功能、處理能力等各種條件的限制。因此,如果可以最大限度地提高應用系統硬件上和軟件上的靈活性,就可以用最低的成本,最少的時間,快速的完成功能的轉換。 本課題的目的在于提出并設計一種基于ARM(Advanced RISC Machines)和CPLD(Complex Programmable Logic Device)的可擴展功能嵌入式系統平臺,并完成了系統的硬件設計和PCI(Peripheral Component Interconnect)橋的固件設計。設計過程中采用美國ALTIUM公司的ALTIUM DESIGNER 6.0 EDA軟件開發了系統的硬件部分。在整個硬件開發環節中,充分采用高速PCB(Printed Circuit Board)的設計原則,并進行全面的電路仿真試驗,保證了硬件系統的高度可靠性。本系統承襲了ARM7系列處理器高性能、低功耗、低成本的優點,并充分考慮到用戶的需要,擴展了多種常用的外部設備接口以及藍牙無線接口等,為將米各種可能的應用提供了完善的硬件基礎。概括總結起來本文具體工作如下: 1.完全自主設計了具有高擴展性的基于LPC2292嵌入式處理器的嵌入式系統應用開發平臺。基于該硬件平臺,可以實現許多基于ARM架構處理器的嵌入式應剛而無需對硬什系統作出大的改變,如多協議轉換器、CAN(Control Area Network)總線網關、以太網關、各種工業控制應用等。并在具體的設計實踐中,總結出了嵌入式系統硬件平臺的設計原則及設計方法。 2.完成了基于CPLD的PCI橋接芯片的同什設計,在ARM硬件平臺上成功擴展了PCI設備,成功解決了ARM處理器和PCI從設備之間通訊的問題。 3.完成了對所開發的嵌入式系統硬件平臺的測試工作,完成了基于AT89C51的PCI測試卡軟硬件設計。基于此測試卡,可以實現對系統中的PCI通訊功能進行有效測試,以保證整個硬件系統正常、高效、穩定地運行。本系統的設計完成,使其可以作為嵌入式應用的二次開發或實驗平臺,用于工業產品開發及高校相關專業的實踐教學。

為了滿足外圍設備之間、外圍設備與主機之間高速數據傳輸,Intel公司于1991年提出PCI(Peripheral Component Interconnect)總線的概念,即周邊器件互連。因為PCI總線具有極高的數據傳輸率,所以在數字圖形、圖像和語音處理以及高速數據采集和處理等方面得到了廣泛的應用。 本論文首先對PCI總線協議做了比較深刻的分析,從設計要求和PCI總線規范入手,采用TOP-DOWN設計方法完成了PCI總線接口從設備控制器FPGA設計的功能定義:包括功能規范、性能要求、系統環境、接口定義和功能描述。其次從簡化設計、方便布局的角度考慮,完成了系統的模塊劃分。并結合設計利用SDRAM控制器來驗證PCI接口電路的性能。 然后通過PCI總線接口控制器的仿真、綜合及硬件驗證的描述介紹了用于FPGA功能驗證的硬件電路系統的設計,驗證系統方案的選擇,并描述了PCI總線接口控制器的布局布線結果以及硬件驗證的電路設計和調試方法。通過編寫測試激勵程序完成了功能仿真,以及布局布線后的時序仿真,并設計了PCB實驗板進行測試,證明所實現的PCI接口控制器完成了要求的功能。 最后,介紹了利用驅動程序開發工具DDK軟件進行軟件設計與開發的過程。完成系統設計及模塊劃分后,使用硬件描述語言(VHDL)描述系統,并驗證設計的正確性。

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。

McCallA Wiley-Interscience Publication JOHN WILEY & SONS, INC.New York • Chichester • Weinheim • Brisbane • Singapore • TorontoCopyright © 2000 by John Wiley & Sons, Inc.speeddigital systems at the platform level. The book walks the reader through everyrequired concept, from basic transmission line theory to digital timing analysis, high-speedmeasurement techniques, as well as many other topics. In doing so, a unique balancebetween theory and practical applications is achieved that will allow the reader not only tounderstand the nature of the problem, but also provide practical guidance to the solution.The level of theoretical understanding is such that the reader will be equipped to see beyondthe immediate practical application and solve problems not contained within these pages.Much of the information in this book has not been needed in past digital designs but isabsolutely necessary today. Most of the information covered here is not covered in standardcollege curricula, at least not in its focus on digital design, which is arguably one of the mostsignificant industries in electrical engineering.The focus of this book is on the design of robust high-volume, high-speed digital productssuch as computer systems, with particular attention paid to computer busses. However, thetheory presented is applicable to any high-speed digital system. All of the techniquescovered in this book have been applied in industry to actual digital products that have beensuccessfully produced and sold in high volume.Practicing engineers and graduate and undergraduate students who have completed basicelectromagnetic or microwave design classes are equipped to fully comprehend the theorypresented in this book. At a practical level, however, basic circuit theory is all thebackground required to apply the formulas in this book.

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.
