Title:
INTER-PROCESSOR COMMUNICATION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS6398761
Kind Code:
A
Abstract:
PURPOSE:To localize an inter-processor communication means in order to cope with various system constitutions by adding a communication memory and a communication processing program to a communication control part. CONSTITUTION:A communication memory 3 is added to a communication control part CCA connected to a common bus to perform communication with CPU 0-n respectively. Both command and response areas are provided to each of these CPU. The part CCA stores a command in a communication area corresponding to the CPU of the remote side and produces an interruption signal 52 which is common to those CPU. Each CPU receives the signal 52 and carries out a processing program to retrieve a command area. When no command is detected, the interruption processing is reset. While a command if detected is analyzed and the response data is set to the corresponding communication area. Then the part CCA searches the response area and reads the response data. Thus an interruption signal can be used in common with those CPU.
