基于ARM微控制器配置FPGA的实现

Implementation of FPGA configuration with ARM-based MCU

介绍了基于ARM内核的ATMELAT 91FR4 0 81微控制器以JTAG的ISP方式配置XILINXXC2S15 0PQ2 0 8FPGA的实现过程。这是一种灵活和经济的FPGA的配置方法。介绍了ISP和JTAG的原理、系统实现的流程、硬件电路设计。

This paper introduced the implementation of XILINX XC2S150PQ208 FPGA configuration with ISP of JTAG mode using ATMEL ARM-based microcontroller AT91FR4081. This is a flexible and economic FPGA configuration method. The following issues were introduced in the paper: JTAG and ISP concepts, system design, hardware schematic design, JTAG driving arithmetic realization and the test result of configuration time.
