METHOD AND SYSTEM FOR BUFFERING INSTRUCTION BY PROCESSOR

PROBLEM TO BE SOLVED: To make a device small-sized by making a necessary silicon area small by using a small-sized limited instruction buffer. SOLUTION: The method for buffering instructions by the processor 12 having a pipeline 20 equipped with a decoding means 28 includes a step for detecting the decoding means 28 stopping functioning, a step for repeatedly making a fetch before the instruction in a memory 16 until the decoding means 28 does not stop functioning, and a step for writing the fetched instructions in the instruction buffer after the decoding means 28 does not stop functioning.
