Abstract

PURPOSE: To shorten the abnormality detection time of hardware by dividing diagnostic microprogram PG into several blocks and by executing instructions in an assigned by a processor that is free because it is in an interruption queue.
CONSTITUTION: Diagnostic microprogram PG starts with control PG part 11, followed by diagnostic PG12 expressing diagnostic contents. Then, PG12 is divided into blocks 1WN, which are individually executable according to the number and the execution time of each block is divided approximately by the execution time of an instruction, which does not accept any interruption for the longest time, among user instructions. One clock of PG12 is addressed to diagnostic address 30, transferred to address register 31 and stored in control memory part 32. If CPU is put in an interruption queue during its calculation processing, the prescribed block of PG12 is transferred to CPU via data register 33 on the basis of the address stored in memory part 32 and the diagnostic micro instructions are executed. Once the abnormality of hardware is detected, an interruption is made to report the abnormality.
