PURPOSE:To execute the picture element arithmetic operation at high speed by a small number of register resources by allocating plural arithmetic units having a multiplying function to one register unit, and actuating them simultaneously by an exclusive instruction. CONSTITUTION:Plural arithmetic units 2 - 5 having a multiplying function are provided, and also, one register designated by an instruction is divided into plural areas, and each arithmetic unit 2 - 5 is allowed to correspond to the respective areas. For instance, a register unit is divided into four areas, and the arithmetic units 2 - 5 are connected to each of them through data lines 10 - 13. Also, in an instruction controller 6, an instruction for actuating simultaneously the multiplying functions of the arithmetic units 2 - 5 is registered in advance, and in accordance with this instruction, a general arithmetic unit 1 executes such processings as an arithmetic operation and a data transfer, etc., to all areas of the register unit. In such a way, the information processing can be executed efficiently. |
