摘要:
An operational processor comprising a data memory for storing data therein, at least one input data storage register for storing the data from the data memory, an arithmetic and logic unit (ALU) for computing the data, and a memory data storage register interposed between the input data storage register and the data memory so as to temporarily store the data from the data memory. An instruction from a host computer or the like is stored temporarily in an instruction register. A control circuit serves to control each register and the ALU in response to the instruction temporarily stored in the instruction register. The instruction partially has a field to indicate transfer of the data from the memory data storage register to the input data storage register. The instruction further has, in its partial division, a field to indicate one input data storage register to which the data is to be transferred.
