Abstract

본 발명은 기억장치를 이용한 제어장치로서 제어를 용이하게 하여 개인용 컴퓨터와 접속되는 시스템에 있어서 사용자 인터페이스, 테스터빌리티(Testability)및 시스템의 신뢰성 향상을 위하여 적용하도록 한 것에 관한 것이다. 종래의 제어장치는 개인용 컴퓨터로 부터 온 제어신호가 올바르게 전달되었는지 여부를 알수없을 뿐만 아니라 만약 잘못 전달됐을 경우 시스템이 오동작하고 있다는 것을 판단하는데 많은 장비를 동원해야 하고, 시스템의 상태를 개인용 컴퓨터에서 알수없기 때문에 컴퓨터로 부터 제어신호가 잘 전달되지 않거나, 현재 시스템에서 일정기간 동작이 필요하지만 컴퓨터에서는 이를 알 수 없으므로 동작중인 시스템의 상태를 갑자기 바꿈으로서 오동작을 일으킬 수 있는 문제점이 있었다. 본 발명은 이러한 점을 감안하여 레지스터 파일을 두어 시스템의 전기능을 개인용 컴퓨터에서 제어가능하도록 하였으며, 시스템의 상태와 그때의 데이터를 읽을 수 있도록 개선하여 검사를 쉽게하며 시스템의 안정도와 신뢰성을 높혀 사용할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device using a storage device, which facilitates control and is applied to improve user interface, testability, and reliability of a system in a system connected to a personal computer. Conventional control devices are not only able to know whether the control signal from the personal computer is correctly transmitted, but also have to mobilize a lot of equipment to determine that the system is malfunctioning if misdirected. Because there is no control signal from the computer, or the current system requires a certain period of operation, but the computer can not know this, there was a problem that can cause a malfunction by suddenly changing the state of the operating system. In view of this point, the present invention has a register file so that all functions of the system can be controlled by a personal computer. The system can be easily read by improving the state and data of the system and improving the stability and reliability of the system. Can be.
