摘要
FPGA在空间系统中已经广泛应用,为了满足系统可靠性和可扩展性的要求,实现FPGA软件的在轨重加载迫在眉睫。根据FPGA的加载配置原理,以Xilinx公司的Virtex-Ⅱ系列FPGA为实例,介绍了FPGA在轨重加载的硬件电路设计以及软件设计。经过实验室测试验证,该设计方法合理可行,满足星载环境下FPGA软件在轨编程及重加载的设计需求。
The FPGA,which is widely applied in outer space systems,needs the ability of on-orbit reloading software to acquire high reliability an flexibility.According to the boot principle of FPGA of XILINX Corp,the paper introduces the design of hardware and software for reloading.The method achieves the ability of on-orbit programming and reloading for FPGA software,which is proved to be reasonable and feasible by testing in laboratory.
