Abstract

PURPOSE: To put both processors into even operation by providing a synchronizing- signal generating circuit in common to both the processors, by providing each processor with a random-mumber generating method, and by determining their priority levels by mutually interchanging remainders obtained by dividing random numbers by certain constant.
CONSTITUTION: Processors 2 and 4, using a synchronizing signal from synchronizing-signal generating circuit 7 for timing, performs generating arithmetic of random numbers stored in memory units 1 and 3 and also divides random numbers of generation results by constants. Remainders of the arithmetic results are mutually interchanged through input-output interface 5 to decide priority levels by processors 2 and 4 and the processor of higher priority performs input-output operation to and from external apparatuses 8-1, 8-2... via input-output interface 6.
