一种PCI总线接口的设计

Design of PCI bus interface

对外设部件互连标准(Peripheral Component Interconnect,PCI)总线接口进行分析和研究,提出一种PCI总线接口的设计方案。利用模块化的设计方法设计PCI总线接口,并介绍主/从接口状态机模块和工作过程。用Modesim软件对PCI接口的硬件设计进行功能仿真。仿真结果表明,该设计能够满足PCI总线的时序要求。

After analysis and research about PCI bus interface,a design of PCI bus interfaces is proposed.The PCI bus interface is designed by using modular design method,master and slave interfaces’ state machine and working process of PCI bus interface is mainly introduced.Modelsim software is used doing function simulation for the hardware design of PCI interface.The simulation result shows that the interface fulfils the timing requirements of the PCI bus
