设计了一种基于 CPCI 总线标准的 PMC 接口载板。载板以 FPGA 为核心，集成了CPCI 接口模块和 DPRAM （双口 RAM ）模块， CPCI 接口模块采用 FPGA+PCI IP 核（软核）解决了系统集成的问题， DPRAM 模块为系统提供了数据缓存功能。环回测试和中断测试解决了在没有子卡 PMC 模块的情况下，读写、验证 DPRAM 空间数据和测试中断响应的问题。此外，还支持子卡 PMC 模块后出线到CPCI 总线。调试结果表明，该载板在嵌入式实时操作系统 VxWorks 下可以稳定运行，正确地读写DPRAM 空间的数据，及时地响应中断，满足了对载板的性能需求。

This paper designs a PMC interface carrier board based on CPCI bus standard. The carrier board uses FPGA as the core design, and integrates CPCI interface module and DPRAM (double RAM) module. CPCI interface module uses FPGA+PCI IP Core(soft) to solve the problem of system integration, the design of DPRAM module provides data cache function for the system, the design of loopback and interrupt test solve the problem of read and write and verification of DPRAM spatial data and test the interrupt response in the case that without PMC card module. In addition, it supports PMC card module to CPCI bus line. The test results show that the carrier board under VxWorks embedded real-time operating system can operate stablely, read and write the correct DPRAM spatial data, interrupt timely response, meet the performance requirements of a carrier board.
