Abstract We discuss the main design concepts for fault-tolerant microprocessors, Instruction Set Architectures (ISA) of microprocessors for space applications and the achievable characteristics considering the KOMDIV microprocessors designed by SRISA. The trade-off between the fault-tolerance, performance and power consumption is considered for microprocessors designed using the silicon-on-insulator (SOI) and bulk CMOS technologies.
Highlights Instruction Set Architectures used for space applications are reviewed and discussed. The main fault-tolerance enhancement techniques are discussed . The fault tolerance of KOMDIV microprocessors is discussed for the first time. The trade-off between the fault-tolerance, performance and power is considered. The characteristics of 1907VM01A4 and 1907VM044 are discussed as the example.
