The present invention discloses a
radiation-resistant design method for an integrated
payload hardware module, belonging to the field of
radiation-resistant design of
hardware modules, which includes the steps: following the requirements of the
general function framework of the module, each digital module is composed of units such as MSU, PU, RU, CMU, and PSE, and the module root devices of all model modules are MSU, CMU, and PSE. Space-grade devices are selected, integrated circuits of other units of the module use non-space-grade devices, and passive devices use space-grade devices; the
radiation resistance of the DSP of PU, the FPGA of PU, and the SRIO switching
chip of RU is realized relying on MSU; the operation of the space-grade FPGA of MSU is monitored by a space-grade watchdog. When single-event upset effects cause abnormal
firmware loading, program operation errors, or even crashes, the watchdog will perform
firmware reloading on it, etc. The present invention has the advantages of
standardization, generalization, high performance, and low cost.
