PURPOSE: To decrease the number of memories and facilitate computer processing, and to facilitate the restructuring of a load block by using two-dimensional cerebellum model computer (two-dimensional CMAC) unit main bodies.

CONSTITUTION: Two output variables distributed by a distributor 11 which outputs plural input variables in two groups are supplied to the two-dimensional CMAC unit main bodies 12a-12n. Those two-dimensional CMAC unit main bodies 12a-12n performs arithmetic with two inputted variables and send one variable out and two-input, one-output two-dimensional CMAC unit main bodies. The two-dimensional CMAC unit main bodies 12a-12n supply their arithmetic outputs to an adder 13, which adds them and outputs the sum. Thus, plural input variables can be processed by the CMAC unit main bodies 12a-12n as minimum units, so the constitution of a CMAC control program is simplified and load structure is also simplified.
