Abstract

PURPOSE:To improve the reliability of a processor, by making the base level a process stage exclusively used for the microdiagnosis and executing microdiagnosis then carrying out the process original to the processor at a level higher than the base level. CONSTITUTION:A unit 16 exclusively used for special process which is added to a main microprocessor 1 contains a control storage and a microprogram sequencer within its own unit, and forms a secondary microprocessor 2 which is independent of the processor 1. The processor 2 forms a group in the form of a firmwave for microdiagnosis. The processor 1 decides the instruction to be processed by each processor and indicates the start of a process to the processor 2 when necessary to start the analysis and process of the next machine instruction.
