COMMUNICATION SYSTEM BETWEEN DISTRIBUTED PROCESSING PROCESSOR

PURPOSE:To execute asynchronously the distributed processing operation of a transmitting side and a receiving side and to improve whole processing time by making communication of a distributed processing section a system through a queue buffer. CONSTITUTION:When sending a meassage from the first distributed processing section 2 to other distributed processing section 2, the message is stored in one of queue elements out of queue buffers constituted on a shared memory 4 of distributed processing section 2 of object of sending according to instruction of a writing point of the transmitted message. In transmitting, a read pointer and a write pointer are read, and checked whether the queue is full or not. If it is not full, the transmitted message is written in a queue element, and the write pointer is made ''+1''. Conversely, the distributed processing section 2 that received the message from the first distributed processing section 2 reads received message in the queue element in order of history and takes out the message according to instruction of the pointer.
