Abstract
본 발명은 CPU 주변 로직 컨트롤을 DMA 기능을 이용 시스템 효율 및 데이타 처리를 신속하게 목적이 있다.An object of the present invention is to use the DMA function of the CPU peripheral logic control, the system efficiency and data processing quickly.
메모리의 구성을 가진 주변로직 다수개를 프로세서에 연결되어 사용하고저 할때 아래그림과 같이 CPU가 하나 하나를 제어하는 방법으로 하면 프로세서의 프로그램 효율이 떨어지게 된 것이다.When a number of peripheral logics with a memory configuration are connected to the processor and used, as shown in the figure below, the CPU controls one by one, which reduces the program efficiency of the processor.
