MULTIPROCESSOR CONTROL SYSTEM

摘要

PURPOSE:To improve a processing speed and to reduce prefix areas on a main memory in a multiprocessor control system by using variably the prefix area of a system control processor on the main memory. CONSTITUTION:The processors IPU 20-22 having independent prefix areas 40-42 on a main memory 6 and prefix addresses corresponding to these areas 40-42 are stored in a fixed area 6-1. When either one of those IPUs gives a processing request to a system control processor SPU 23, the area 6-1 is retrieved by the SPU 23 and the prefix address of the IPU that had a processing request is set at a prefix register 27 as a prefix address of the SPU 23. Then the SPU 23 processes data on the prefix area of said IPU.
