In-system Programming of FPGA System with DSP and JTAG Interface
摘要
Abstract
SRAM-based FPGA has higher power consumption at high temperature,and its memory configuration is invalid when power-fail occurs.Besides,FPGA needs to be upgraded in some systems.A in-system programming method for FLASH-based FPGA is realized by using RAM as the stream carrier of configuration code and DSP as master controller.Configuration code of FPGA is downloaded to external RAM through serial ports of DSP.The clearing and programming of Flash and in-system programming of FPGA are implemen-ted through driving FPGA′s JTAG interface by DSP′s GPIO.Experimental results show that the system can work stably at 1 50 de-grees.The method has high reliability and convenient operation.关键词
