ABSTRACT:
In a data transmission apparatus, a plurality of data processing modules are used and required sequence setting is performed to a port sequencer of input/output ports of each data processing module. The daisy chain transfer of the selective data transfer, the load distribution data transfer, the collective data transfer is combined between the data processing modules, thereby the data transmission is performed efficiently at high speed.
