Abstract

PURPOSE: To increase the operating ratios of main and subordinate processors by forcing the subordinate processor to execute a program to be allotted on the basis of information transferred and by permitting the main processor to collect the execution end signal of the subordinate processor.
CONSTITUTION: Main processor 1, after setting a parameter, executes a prescribed fork instruction and informs subordinate processor 2 of the result. In response to the information, processor 2 after saving information on program P2-Pn in process of execution at that time is forced to execute program P1 to be allotted on the basis of the information transferred from processor 1. Here, processor 2, when completing the execution of program P1 to be allotted, informs processor 1 of that and restarts original program P2-Pn, and processor 1 executes a predetermined joint instruction to collect the execution completion signal of processor 2, thereby increasing processor operating ratios.
