<p>A data communication technique is provided which realizes an efficient combination of a plurality of information processing apparatuses (GSM) when performing a higher level processing by use of the GSMs. There are included four GSMs (1), a slave MG (merger)(3) for merging the data outputted from the GSMs (1), and a main MG (200) for merging the data outputted from four slave MGs (3). The data of unit data length outputted from the GSMs (1) are stored in parallel in a register. The data stored in the register are serially read out by unit data length to form a serial data. When a modified data exists in the serial data, an auxiliary data for identifying the modified data is added to a predetermined position of the serial data. Thereafter, the serial data is outputted to the main MG (200). As to the data to be outputted from a main SYNC (300) to the GSMs (1), parallel data are copied and propagated to all the GSMs (1) during the same time period.</p> |
