【摘要】：PCI(Peripheral Component Interconnect)总线因其具有众多的功能、强大的兼容性和独立于处理器等很多优点，在计算机总线市场上独领风骚，并且在芯片级设计中，经常使用PCI总线作为主机接口。随着嵌入式系统的发展，特别是SOC(System On a Chip)技术的飞速发展，IBM系列的处理器在嵌入式系统芯片设计中得到了广泛的应用。PLB(Processor Local Bus)总线被IBM用作片上处理器总线，因此在使用PCI接口的嵌入式系统芯片设计中，PCI-PLB桥就成为了必备的接口模块。本文针对基于IBM系列处理器的SOC系统，，采用了PCI-PLB桥模块作为主机接口，设计实现了SOC系统与其它PCI主设备、从设备的PCI通信接口。验证仿真结果表明，在PCI总线工作频率为33MHz，总线宽度为32位的情况下，该PCI-PLB桥可以以较高传输效率来实现PCI设备与SOC之间的相互通信。本文首先对PCI总线和PLB总线协议进行了介绍，其中包括总线命令和总线操作时序。并且对PCI-PLB桥的体系结构和功能进行了深入的研究，PCI-PLB桥包括两个传输通道，一个是PCI到PLB方向的向内传输通道，另一个是PLB到PCI方向的向外传输通道。在对PCI-PLB桥研究的基础上，进行了集成在桥中的PCI仲裁器的设计。其次在基于SOC的PCI通信接口设计部分，构建了SOC系统整体架构，实现了SOC系统与其它PCI主设备、从设备的PCI通信接口。最后论文重点讨论了验证平台的搭建、验证方法和验证原理，完成了模块级和虚拟平台级的验证。
[Abstract]:PCI(Peripheral Component Interconnect bus has many advantages, such as numerous functions, strong compatibility and independence from processor, and so on, so it dominates the market of computer bus. PCI bus is often used as host interface in chip level design.Therefore, PCI-PLB bridge has become a necessary interface module in the design of embedded system chip using PCI interface.In this paper, for the SOC system based on IBM series processors, the PCI-PLB bridge module is used as the host interface, and the PCI communication interface between the SOC system and other PCI main devices and slave devices is designed and implemented.The simulation results show that the communication between PCI devices and SOC can be realized with high transmission efficiency under the condition that the frequency of PCI bus is 33MHz and the bus width is 32 bits.This paper first introduces PCI bus and PLB bus protocol, including bus command and bus operation timing.Furthermore, the architecture and function of PCI-PLB bridge are deeply studied. The PCI-PLB bridge includes two transmission channels, one is the inward transmission channel from PCI to PLB, the other is the outward transmission channel from PLB to PCI.Based on the research of PCI-PLB bridge, the design of PCI arbiter integrated into the bridge is carried out.Secondly, in the part of PCI communication interface design based on SOC, the whole structure of SOC system is constructed, and the PCI communication interface between SOC system and other PCI main devices and slave devices is realized.Finally, the paper focuses on the construction of verification platform, verification method and verification principle, and completes the verification of module level and virtual platform level.
