VPX平台的多板卡FPGA动态配置方法

陈昌明,邵高平,刘小蒙,党力明,高飞   

  1. 针对VPX平台板卡的FPGA通常采用上电时从非易失性存储器主动加载配置数据的方式,存在灵活性较差的缺点。文中提出了一种基于CPU+SPI总线+CPLD的多板卡FPGA动态配置方法,可在不开箱的情况下对平台内各板卡FPGA进行动态配置。经测试,该方法配置10.9 MB大小的数据用时约为7 s,具有较好的灵活性和可靠性。

Multiple Boards FPGA Dynamic Configuration on VPX Platform

CHEN Changming,SHAO Gaoping,LIU Xiaomeng,DANG Liming,GAO Fei   

  1. Currently,FPGA on VPX platform board usually loads configuration data from nonvolatile memory initiatively when power-on occurs,which has the disadvantage of inflexibility.This paper presents a multiple boards FPGA dynamic configuration method based on CPU+SPI bus+CPLD which offers FPGA configuration on boards without opening the box on VPX platform.It takes about 7 seconds to configuring data of 10.9 MB by this method with good flexibility and reliability.

Abstract:

Currently,FPGA on VPX platform board usually loads configuration data from nonvolatile memory initiatively when power-on occurs,which has the disadvantage of inflexibility.This paper presents a multiple boards FPGA dynamic configuration method based on CPU+SPI bus+CPLD which offers FPGA configuration on boards without opening the box on VPX platform.It takes about 7 seconds to configuring data of 10.9 MB by this method with good flexibility and reliability.
