摘　　要：CPCI总线为不同应用的高速数字系统提供了一个通用、开放的平台,它充分发挥了PCI总线的高性能、低成本、通用操作系统等特点,而LVDS接口技术无疑也将成为解决高速数字系统数据传输的首选方案。提出了一种基于FPGA实现CPCI总线接口与LVDS接口的新方法,CPCI总线与自定义LVDS接口相结合,在不降低系统通用性的前提下,提高了系统实时并行处理能力。由于所有接口均由FPGA来实现,因此提高了系统的可重构性。CPCl bus provides a general, open platform for different high-speed digital system. It sufficiently exerts PCI＇ s characteristics of high-performance, low-cost and universal-OS. LVDS interface technology has undoubtedly become the optimal scheme to resolve the transmission problem of high-speed digital system. A new method of implementing CPCI bus interface and LVDS interface based on FPGA was brought forward. By using the CPCI bus and custom LVDS interface, the ability of parallel processing of the system was improved without reducing the system universality. For all interface being realized by FPGA, the reconfigurable ability of the system is improved.
