Abstract

PURPOSE:To increase an arithmetic speed by operating two arithmetic parts, having different functions, in parallel in an arithmetic controller used for calculation on a microprogram control basis. CONSTITUTION:When a microinstruction to an arithmetic part BPH9 performing arithmetic regarding variable-length data is sent under the control of a control part 7, the arithmetic part BPH9 starts processing data. Until the BPH9 completes the processing, preparations for several microinstructions are completed and those instructions include a microinstruction for an arithmetic part ALU8 performing normal arithmetic without fail. Then, when the control of the control part 7 comes to the microinstruction for the ALU8, it is executed by the ALU8 and during the period, the BPH9 processes data.
