ABSTRACT:
A data driven type information processor includes a firing control unit, an operation unit, and a program storage unit. The firing control unit sequentially receives data packets, and detects a data packet which stores paired data, and outputs the detected data packet. The operation unit receives a data packet output from the firing control unit, operates on the contents of the received data packet, stores the operation result in the received data packet, and outputs the received data packet. The program storage unit receives the data packet output from the operation unit, and reads a program word formed of a plurality of program word sets from a prestored data flow program by addressing based on the contents of the received data packet. Then, the program storage unit outputs no data packet if every Valid flag corresponding to each program word set in the read program word is invalid (data packet erasing), or generates a data packet corresponding to each of at least one program word set whose Valid flag is valid in the read program word, additionally stores data of the operation result in each generated data packet, and outputs each generated data packet (data packet copy). Consequently, data packet erasing or data packet copy by one addressing can be carried out on reading a program in the program storage unit.
