ABSTRACT:
The assignment result reception circuit11receives the accumulation assignment result from the external portion, and sends the already-assigned input port and output port information to the assignment request mask circuit12. The assignment request mask circuit12uses the already-assigned input port and output port information received from the assignment result reception circuit11, performs the mask process on the connection assignment request received from the external portion, and sends its result to the M×N scheduler circuit13. The M×N scheduler circuit13determines the assignment of the port connection in accordance with the information received from the assignment request mask circuit12, and sends the connection assignment result to the external portion and the assignment result transmission circuit14. The assignment result transmission circuit14carries out the logical OR between the connection assignment result received from the M×N scheduler circuit13and the accumulation assignment result received from the external portion, and outputs to the external portion. Thus, it is possible to carry out the connection assignment effectively with small waste.
