The harsh radiation environment of space, the propensity for SEUs to perturb the operations of silicon based electronics, the rapid development of microprocessor capabilities and hence software applications, and the high cost (dollars and time) to develop and prove a system, require flexible, reliable, low cost, rapidly developed system solutions. Consequently, a reconfigurable Triple Modular Redundant (TMR) System-on-a-Chip (SOC) utilizing Field Programmable Gate Arrays (FPGAs) provides a viable solution for space based systems. The Configurable Fault Tolerant Processor (CFTP) is such a system, designed specifically for the purpose of testing and evaluating, on orbit, the reliability of instantiated TMR soft-core microprocessors, as well as the ability to reconfigure the system to support any onboard processor function.
