Abstract
A data processing device comprises an instruction decoding unit for decoding a code of either a division instruction or a remainder instruction applied thereto, the instruction code having a size field for storing data size information. When a control unit receives a decoded result from the instruction decoding unit, the decoded result indicating the data size information stored in the size field of the instruction code, it presets a number of times that one loop iteration comprised of steps required for executing either the division instruction or the remainder instruction is to be carried out, based on the data size information. An ALU disposed within an arithmetic unit performs the loop iteration for either the division instruction or the remainder instruction only the number of times preset by the control unit.
