Satellite Control and Data Processing Unit Software Design Based on Multi-core Processor

Satellite control and data processing unit is the core of satellite information system, which is the key to realize autonomous flight, autonomous management and improve reliability and security of satellite. Currently, the improvement of the performance of single-core processor is restricted by Moore's law and the power consumption wall. The computing power of the satellite control and data processing unit using a single-core processor can no longer meet the requirements of the satellite's increasing control frequency, autonomous operation capability, and fault diagnosis capability. Based on the research of multi-core processors and the analysis of satellite control and data processing systems, this paper proposes an architecture of satellite control and data processing unit embedded software system based on multi-core processor, which significantly improves the processing performance of satellite information systems. Based on this architecture, it is possible to further improve the autonomous operation capability and fault diagnosis capability of the satellite system.
