Multifunctional configurable single particle radiation resistance system and method

Abstract

The invention discloses a multifunctional configurable single particle radiation resistance system and method. A key parameter loading module of a monitoring unit loads a monitoring configuration parameter stored in an external memory to the monitoring unit; the monitoring configuration parameter is put in a storage file generated in a set format; a central control module of the monitoring unit executes program loading after a target FPGA is powered on; the central control module monitors a loading completion confirmation signal of the target FPGA and waits for program loading success of the target FPGA; and when the loading completion confirmation signal of the target FPGA is received, the program loading completion of the target FPGA is confirmed. Different working interfaces can be selected for performing radiation-resistant reinforcement design on any quantity of FPGAs with backward reading functions only by modifying the monitoring configuration parameter in the external memory, so that multifunctional configurable reinforcement design of multiple SRAM type FPGAs can be realized.

Description

technical field [0001] The invention relates to space radiation effect reinforcement technology, in particular to a multifunctional and configurable anti-single event radiation system and method. Background technique [0002] With the shrinking of CMOS process size, integrated circuits working in space environment are more and more seriously affected by failure problems caused by single event errors. Future data relay satellites, broadband communication satellites, remote sensing satellites, radio reconnaissance satellites, navigation satellites, and early warning satellites all need powerful on-board processing platforms (OPP, On-board Processing Platforms) to ensure space support capabilities. These on-board processing The platform is mainly built with FPGA (Field Programmable Gate Array, Field Programmable Gate Array), DSP, ADC, DAC and other chips as the main components. And these large-scale integrated circuit devices, especially SRAM (Static RAM, static random access ...
