Abstract
PURPOSE: To make mutual communication between processors possible through irreducible hardware by allowing two processors, performing transmission and reception of data, to use only flag messages transmitted from respective processors to party processors.
CONSTITUTION: The 1st and 2nd processors 1 and 2 consist of microcomputers, and microcomputer 1 outputs data synchronous flag 1 to port 02A at the same time as the transmission of data 1 to port 01A. Answering to flag 1, microcomputer 2 receives data 1 and sends flag 2 out to port 02B. Answering to flag 2, microcomputer 1 sends next data 1 and flag 1 and carries on the transmission until flag 2 from microcomputer 2 arrives until the fixed number of times. To perform data transmission from microcomputer 2, ready-to-receive flag 1 is sent from microcomputer 1 firstly and microcomputer 2 sends data 2 answering to it and also sends synchronous flag 2. Answering to it, microcomputer 1 receives the data and also sends flag 1 and microcomputer 2 keeps on sending the data until it receives flags 1 fixed times.
