XAPP137 - Configuring Virtex FPGAs from Parallel EPROMs with a CPLD (PDF)
查看文档详情
Previous generations of Xilinx® FPGAs supported a Master Parallel Configuration Mode which allowed the FPGA to configure itself directly from a parallel (byte wide) PROM. The Virtex® family of Xilinx FPGAs does not utilize a Master Parallel mode. This application note describes a simple interface design to configure a Virtex device from a parallel EPROM using the SelectMAP configuration mode.
