Trusted Method of Software Core Migration Based on Loongson Processor

Computer systems use migration mode to copy the software core from low-speed ROM to high-speed RAM. Aiming at the trustable requirements of software migration, based on the unique instruction sets of Loongson processor, this paper analyzes the startup process of Loongson processor, and puts forward the implementation ways of kernel migration trustable technology, including product information verification, CRC verification and information digest verification, so as to find out the defects and hidden risks in kernel migration in time. Based on actual case, the feasibility of the technical approach is verified. The results show that this technical approach can effectively improve the reliability of code migration, ensure the safety of software operation, and have certain anti-attack ability, which provides a feasible implementation reference for the research and development core software of information equipment.
