Abstract

The invention provides a detection and restoration system and method for a programmable computing unit for space information processing. The invention relates to a detection and restoration system and method for a programmable computing unit and aims to solve the problems that in general, the conventional way needs to consume computer resources and power for more than 3 times additionally for detection and restoration and thus performance improvement and low power consumption requirement of an FPGA in space computation are greatly influenced. The detection and restoration system for a programmable computing unit for space information processing comprises an input data cache module, a data segmented check control module, a data processing module, a computing result cache module, a test result check module, a result output control module and a function restoration control module. The system and the method are used for the field of aerospace data processing.

Description

technical field [0001] The invention relates to a detection and repair system and method for a programmable computing unit. Background technique [0002] With the continuous improvement of load performance, the improvement of the control accuracy of the attitude and orbit control system, as well as the space CPS (Cyber-Physical Systems) system, on-orbit autonomous operation management, on-orbit system health management, equipment artificial intelligence and other advanced technology concepts in satellite technology The gradual expansion of the field poses a higher challenge to the computing and information processing capabilities of the On Board Computer (OBC). Due to the lack of core technology with independent intellectual property rights and the blockade of sensitive technologies by foreign countries, the performance of my country's spaceborne computer system is far behind the world's advanced level, and its development is slow, which restricts the improvement of the over...
