摘要
为了满足PCI总线在实际应用中实时性和可靠性的要求,在对PCI总线协议的研究基础上,提出并设计一种基于PCI协议,由FPGA负责控制的总线模拟器的方案。该方案在硬件上以PCI总线控制器和可编程逻辑器件(FPGA)为基础,结合EDA技术和硬件描述语言(VHDL)实现了一款适用于某军用计算机的总线数据模拟器。通过在ISE 10.1平台下对程序进行编译和综合,并在ISE simulator环境下进行了验证,证实了该方案的可行性。在某项目中的应用中,证明该方案能够满足实际通信的要求。
To meet the high real-time and high reliability of PCI-bus in practical application,by studying the principle of PCI bus communication protocol,a scheme of bus data simulator based on the research of PCI bus protocol controlled by FPGA is put forward.This scheme is based on the PCI communication controller and FPGA.It combines with EDA technology and VHDL to realize a bus data simulator which is suitable for military computer.With testing and simulating on ISE Simulator,the program is complied and synthesized on ISE 10.1 platform.The application in a project proves that this scheme can meet the requirements of practical communication.
