Embodiment Construction
[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0039] According to the design characteristics of my country's spacecraft, the invention divides the single event soft error protection into four levels, and uniformly designs each level of protection with different means and strategies, forming a hierarchical and layered single event soft error protection system structure. The single event soft error protection classification method is as follows:
[0040] Level 0 (level 0): Device stand-alone level protection.
[0041] Device-level protection implements anti-single event soft error reinforcement from the aspects of materials, processes, components, etc., without hardware circuit or software intervention; stand-alone level protection is realized through the design of hardware circuit or software itself, without the need for ground and spaceborne software to implement single-event soft error.
