Abstract
An input port receives input data X, generates input packets by adding generation numbers and node numbers indicative of prescribed destinations, in the order of reception, and in addition, generates a data packet from a separately input clock signal. The input data packet is written to an image memory using the generation number in the packet as an address signal, or read from the image memory using the generation number in the data packet as an address signal. Operation is performed in accordance with the input data packet or the data packet read from the image memory by a memory interface, and the processed data packet is output to the outside of a data driven engine, a memory interface or a data driven type processor.
