With improvement of the performance in satellite,the performance in satellite is restricted with the solid-state recorder which has small capacity and single memory cache.It is the exact problem to develop the solid-state recorder which has high real-time,big capacity and high stabilization.Because aerospace electronic system can′t be repaired,the stabilization and dependability requirements are very high in system.However,the devices can be selected are not so many.FPGA and SDRAM devices are used to make a ping-pong memory cache hardware configuration to take the place of single memory cache structure in the past project in the paper.The real-time of solid-state recorder is very high and the memory capacity is very big.There are plenty of problems in the research process and correlative resolvents are put forward about the problems.And the resolvents are the innovation too.The solution can be applied to all relevant civilian system,the stability and reliability of a similar system are enhanced.
