The Design of On-board Programming for Satellite DSP Software
Yong Huang · Guidance and Fuze · 2011
The Digital Signal Processor(DSP),which is widely used in outer space system,needs on-board programming ability to acquire high reliability and flexibility against the space radicalization.The on-board software update and multi-system boot are realized by modifying the code of the Bootloader according to the boot principle of DSP,which makes long-distance problem solving and function expanding possible.Experiments show that this system can improve the reliability of system and decrease the probability of system crash due to some failure.
