ABSTRACT:
An instruction fetch control method is generally arranged so as to have a plurality of instruction buffers, issue an instruction read request to a memory when a part of the instruction buffers becomes in an empty state and store a fetched instruction in the instruction buffer in an empty state. A flag is provided for specifying another instruction buffer which becomes in an empty state after the instruction stored in the instruction buffer is transmitted to a decoder. The quantity of instructions to be stored in the instruction buffer is made variable in accordance with output of the flag latch, and the fetched instruction is stored in the instruction buffer in an empty state. This arrangement enables a plurality of instructions fetched upon an instruction read request to be stored in the empty instruction buffers, thereby reducing the number of read requests issued.
