  • Detection And Correction Of Errors (AREA)

Abstract

PURPOSE: To detect malfunctions of a micro address register or peripheral circuits of it by providing information for checking errors of contents of this register in micro instructions and checking errors of contents of this register.
CONSTITUTION: Micro address register 4 stores addresses of a microprogram, and memory 1 stores micro instructions having information for detecting errors of register 4. Meanwhile, micro address check register 7 sets information for detecting errors, and check circuit 9 uses this set information to detect errors of contents of register 4. Thus, malfunctions of register 4 and peripheral circuits of it can be detected.
