摘要
Abstract
To address hardware immutability and limited on-board random access memory(RAM)of on-orbit satellite,a reconfiguration system is designed in which FPGA programs whose uplink injections exceed buffer capacity are managed in batches.The existing RAM resources are used to verify the programming data injected in each batch,and,when errors occur,the injections are re-transmitted.Upon completion of a single-batch injection,the data are written to a one-way NAND Flash,the RAM region is cleared,and preparations are made for the next batch of wri-ting.Through multiple batches of injection,a complete set of reconfiguration programming data is constructed in the Flash,and,ultimately,successful programming of the FPGA is achieved through a single one-way read of the Flash.Results from ground tests and on-orbit applications indicate that the design is applicable to on-orbit satellite FPGA reconfiguration and resolves the challenge posed by reconfiguration programming data exceeding buffer capacity.关键词
