Payload reconfigurable technology based on antifuse FPGA

摘要:

针对在轨卫星功能维护、扩展和更新的需求，设计一种星载FPGA可重构方法。通过硬件三模冗余、软件三模比对，提高星载信号处理FPGA配置的可靠性；通过地面向卫星配置FPGA发送擦除、写、读指令，实现星载配置数据存储FLASH芯片的擦除、写、读操作，从而实现星载信号处理FPGA的重构，进而可以实现有效载荷功能的在轨更新或升级，减少硬件重复开发，降低成本。

Abstract:

This paper designs a kind of on-board FPGA reconfigurable method, improves configuration reliability of onboard signal processing FPGA by making use of hardware three-mode redundancy and software three-mode comparison. By sending the erase, write and read instructions to the satellite configuration FPGA, the erase, program and read for the onboard data storage FLASH are realized, so as to realize the reconfiguration of the onboard signal processing FPGA, and then realize the on-orbit update or upgrade of the payload function, reduce the repetitive development of hardware and the cost.
