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

摘要

The present invention provides data communication technology for improving the efficiency of cooperation of two or more information processing units (GSM) for more sophisticated processing. According to the present invention, there are provided four GSMs 1, a sub-MG (merger) 3 for merging data supplied from the GSMs 1, and a main MG 200 for merging data supplied from the four sub-MGs 3. Data supplied from the GSMs 1 are stored in parallel in a register on a unit length basis. Then the data stored in the register are serially read on the unit length basis to form serial data. When the serial data contain modified data, auxiliary data for identifying the modified are added to a predetermined portion of the serial data and are supplied to the main MG 200. On the other hand, parallel data to be supplied from a main SYNC 300 to each GSM 1 are copied, and the copies of the same parallel data are propagated over all the GSMs 1 at the same time.
