Abstract

A data driven processor includes an output processing unit outputting a data packet outside the processor while referencing a branch control parameter register group. In the register group, a processor number/generation number specifying parameter P/G, a branch comparison parameter RM, and a branch comparison data parameter RD are stored. At the time of output of the data packet, the output processing unit reads out any one of a processor number and a generation number in the data packet according to parameter P/G, and sends out the data packet to any one of output ports OA and OB according to the result of predetermined operation processing using the read out number and parameters RM and RD. When a plurality of processors which operate as described above are connected to each other to carry out processing simultaneously while inputting/outputting a data packet, a data path among the processors can be set and changed easily according to any of the processor number and the generation number in the packet.
