Abstract

본 발명은 마이크로프로세서의 메모리 사용방법에 관한 것으로서, 특히 마이크로프로세서의 외부 메모리의 효율적인 사용 방법에 관한 것이다.The present invention relates to a method of using a memory of a microprocessor, and more particularly, to a method of efficiently using an external memory of a microprocessor.

본 발명에 따른 마이크로프로세서의 외부 메모리를 효율적으로 사용하는 방법은 하이 레벨 언어의 매크로 기능처럼 반복적인 머신명령어들이나 바이트수가 많은 머신 명령어를 마이크로프로세서 내부의 매크로레지스터에 매크로로 정의하고 외부 메모리의 단위 바이트 크기의 매크로를 명령으로 콜하여 사용함으로써 외부 메모리의 효율적인 사용을 제공한다.In the method of efficiently using the external memory of the microprocessor according to the present invention, a repetitive machine instruction or a machine instruction having a large number of bytes, such as a macro function of a high level language, is defined as a macro in a macro register inside the microprocessor, and a unit byte of the external memory is used. Calling and using a macro of size as a command provides efficient use of external memory.
