제어전용 마이크로 프로세서와 PC간에, 본 연구에서 제안하는 이중 포트 램을 이용한 병렬처리 방식으로 하드웨어를 설계 제작하고, 제어응답실험을 행한 결과 기존의 범용 A/D & D/AC 카드로 수행하기 어려웠던 2개 이상의 제어 대상을 제어하고 모니터링 하는 작업을 원활히 수행할 수 있음을 확인하였다

This paper presents the data parallel processing method between a PC and a micro-controller. To implement the method a dual port RAM for a real time data processing is used. In general an A/D & D/AC card is used to send or receive the data into or from the external plant and the PC does only the computation of the A/D and the D/A data because the A/D & D/AC card does not have the ability of computation. In this study, a data parallel processing method in which the PC and micro-controller own a common dual port RAM, is introduced, so that the PC can compute the A/D and D/A data and control the plant simultaneously. The PC system with a micro-controller and the common dual port RAM is designed and its effectiveness is investigated experimentally considering the performance of both the computation of data and the controlling and monitoring the external plant
