The hardware architecture of a modular redundant and reconfigurable RISC- (reduced-instruction-set-computer) based fault-tolerant computer system that meets the high availability requirements of real-time applications is presented. A range of redundancy levels is available, and these levels can be defined by the user during the initial or any subsequent system configuration process. Fail-operational capabilities are provided for processor, memory, internal bus, I/O, and power source subsystem failures, and an optional uninterruptible power supply is available. The system protects both stored and output data from corruption upon failures, and the system's fault tolerance and redundancy are transparent to the user. Overall, the fault-tolerance functions are closely integrated with diagnostic software to facilitate system maintenance and repair
