Abstract
본 발명은 단일 회선 비동기 통신 방식에 의한 다중 포트 시스템의 제어데이타 수신장치에 관한 것이다. 본 발명에 따른 다중 포트 제어시스템은 하나의 프로세서에 다수의 데이타 수신 장치가 단일 회선으로 접속된다. 각각의 데이타 수신장치는 마이크로프로세서로부터 단일 회선을 통해 직렬 전송되는 데이타중의 스타트 비트를 검출하는 스타트 비트 검출부와, 스타트 비트 검출에 따라 데이타의 크기를 카운트하는 카운터와, 타운터에 의해 필요한 데이타를 수신완료할 때 직렬 데이타를 시프트 하여 병렬로 변환하는 데이타 변환부와, 상기 데이타중의 제어코드를 판독하여 포트 식별 신호를 발생하는 디코더와, 상기 디코더의 포트 식별신호에 따라 상기 데이타 변환부로부터 전달되는 데이타를 선택적으로 다중 포트로 출력하는 래치 회로를 포함한다.The present invention relates to a control data receiving apparatus of a multi-port system by a single line asynchronous communication method. In the multi-port control system according to the present invention, a plurality of data receiving devices are connected to one processor by a single line. Each data receiving apparatus includes a start bit detection unit for detecting start bits in data serially transmitted from a microprocessor through a single line, a counter for counting the size of data in accordance with the start bit detection, and data required by a townter. A data converter which shifts serial data upon conversion and converts the data in parallel, a decoder which reads a control code in the data and generates a port identification signal, and transmits the data according to the decoder's port identification signal. And a latch circuit for selectively outputting data to multiple ports.
