Abstract
Mars rover mission carried many types of cameras, which need to complete complex science exploration and research task, it’s hard to meet the demands of image paralleled storage and access operations using the traditional Chang-E’s multiplex and storage scheme. Due to the speed and memory size limitation of on-board highly reliable radiation-hardened computer, the ground computer file system cannot be realized. This paper designed a FPGA based hardware paralleled image file system to meet the requirement of image data storage management in the Mars rover explore task. In addition the multi-type and multi-camera data file storage system of MARS rover is implemented in the actual rover’s computer which provided multi-partition paralleled reading and writing of multi-image files and on demand addressing and copying functions while ensuring high reliability.
