In a system for executing distribution, arrangement and collection of array data between a host processor and plural processor elements, control parameter regarding array data to be transferred and an identification number assigned to each data receiver are set beforehand to a data receiver of each processor element. Data sequentially sent out onto a data bus with synchronization with a strobe signal from the data transmitter of the host processor are fetched selectively according to a data transfer allowance signal generated based on the control parameter and the identification number. The fetched data is written into a memory with a discrete address.
