Radiation Testing of a Multiprocessor Macrosynchronized Lockstep Architecture With FreeRTOS

Nowadays, high-performance microprocessors are demanded in many fields, including those with high-reliability requirements. Commercial microprocessors present a good tradeoff between cost, size, and performance, albeit they must be adapted to satisfy the reliability requirements when they are used i...
