PURPOSE:To make simultaneous communications between a host processor and plural processors by comparing processor numbers with a number stored in a register, dimension by dimension, and receiving a command according to the comparison result. CONSTITUTION:A PE checks whether an (x)-directional number 502 and a (y)- directional number 503 sent from a host processor are zero or coincident with two-dimensional PE numbers 701 and 702 which are stored in reference registers respectively and assigned to the PE by using comparators 704 and 707. Namely, when the number 502 is zero or coincident with the numbers 502 and 701, a coincidence signal is outputted. Similarly, when the number 503 is zero or coincident with the numbers 502 and 702, the coincidence signal is outputted. Those coincidence signals are ANDed by an AND gate 709 to decide two-dimensional PE numbers in an (x)-row and (y)-column direction. Then, those coincidence signal are used to determine whether or not a command 504 from the host processor is inputted from an input part 710 or not. |
