摘要
分析了PCI接口的几种实现方法 ,并根据具体应用电路选择了能够实现PCI接口与DSP之间无缝连接的芯片PCI2 0 40。介绍了PCI2 0 40和TMS3 2 0VC5 410的主要性能特点与控制方法 ,描述了实现一个集高速数字信号输入、数字控制信号输出、模拟信号的采集与处理、模拟信号产生为一体的多功能接口电路的设计方法 ,给出了电路的主要功能与指标 。
Several methods of realizing PCI interface are compared in this paper.The PCI2040 chip which provides a seamless connection between PCI interface and DSP is selected. The main features and the control methods of PCI2040 are introduced. The method of realizing a multi-functional interface card is described which can perform the input of high-speed digital signals, the output of digital control signals, the sampling and processing of analog signals and the generation of analog signals. The main features of the card is also described. Finally the methods of developing a driver are introduced.
