PURPOSE:To shorten the arithmetic processing time of an arithmetic processor, by previously storing repeatedly executed instruction codes in the processor. CONSTITUTION:An instruction buffer 20 which stores an instruction code string in accordance with an instruction read from a memory 14. The instruction buffer 20 can make reading/writing at a high speed and the reading/writing data are given and received through an internal bus 10. When the same instruction is executed repeatedly, the instruction is executed by fetching the instruction code from the instruction buffer 20. Therefore, high-speed data processing is made possible. |
