可在线升级的FPGA并行配置方法的实现

The Implementation of the parallel configuration of FPGA that can be updated online

针对基于SRAM结构的FPGA,详细介绍了一种采用可在线升级的SST89V564RD微处理器对其进行上电PPA(被动并行异步)配置,不仅实现了FPGA的在线配置,而且通过微处理器的IAP技术,还能完成FPGA配置信息甚至更换FPGA芯片后整个系统的在线升级。

Gainst the FPGA that Based on the structure of the SRAM, the thesis introduced the SST89V564RD MPU that can be updated on line to do some power-on PPA configuration for FPGA. This not only finished the FPGA on-line configuration but also finished the on-line updating the FPGA configuration information and even the whole system after renewing the FPGA chips by the IAP technology of MPU.
