DATA COMMUNICATION SYSTEM AND METHOD, COMPUTER PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a data communication technology for efficiently linking a plurality of information processors (GSM) to each other in a higher-level processing by use of the GSM. SOLUTION: This system is provided with four GSM 1, four slave mergers(MG) 3 for integrating the data outputted from each GSM 1, and a main MG 200 for integrating the data outputted from the four slave MG 3. The data for every unit data length outputted from each GSM 1 are stored in a resistor in parallel, and the data stored in the register is serially read for every unit data length to form serial data. When changed data are present in the serial data, auxiliary data for identifying which is the changed data are added to a prescribed part of the unit data length, and outputted to the main MG 200. For the data to be outputted from a main SYNC 300 to each GSM 1, the parallel data are copied and propagated to all the GSM 1 in the same time.
