基于PCI总线配置FPGA的技术

Configuration Technology of FPGA Based on PCI Bus

FPGA广泛应用于现代仪器中,但是FPGA的固有配置方式限制了仪器测量功能的扩展和升级。本文分析了FPGA的配置时序,介绍了基于PCI总线和CPLD来配置FPGA的方法,实现了FPGA的在线重配置,方便了仪器测量功能扩展和升级。

FPGA is widely used in modem instrument, but the traditional configuration scheme of FPGA limit the extension and upgrade of instrument＇s function. This paper analyzes the configuration clock, introduces the configuration scheme based on PCI bus and CPLD which realizes online configuration of FPGA and extension and upgrade of instrument＇ s function conveniently.
