Abstract

이 발명은 펄스 신호 카운트 방식을 이용한 데이타 송. 수신 방법에 관한 것으로 로서 리더펄스와 펄스신호의 갯수로 정보 데이타의 내용이 구분되는 데이타 펄스 및 블랭크 영역의 시리얼 데이타 포맷으로 펄스 신호를 원-라인으로 수신하여 리더 펄스를 인식하고 데이타 펄스 수를 카운트하여 정보 데이타의 내용을 인식하는 방법으로 데이타를 송수신함으로서 종래의 스트로보신호나 클럭 신호용 데이타 라인을 줄일수가 있어서 각 소자의 핀-포트를 절감하여 칩사이즈를 감소시키는 효과와, 고주파의 클럭신호에 의한 노이즈원도 재거하여 동작에러방지와 성능의 향상 시킬수 있어, 하이스피드를 요구되지 않고 정보량이 적은 시리얼 데이타를 송수신하는 경우에 사용하면 더욱 효과적이다.The present invention is a data song using the pulse signal count method. Receiving method, which receives the pulse signal in one-line in the serial data format of data pulse and blank area where the contents of information data are divided by the number of reader pulses and pulse signals, and recognizes the leader pulse and counts the number of data pulses. By transmitting and receiving data in a manner of recognizing the contents of the information data, it is possible to reduce the data line for the conventional strobe signal or clock signal, thereby reducing the pin-port of each device to reduce the chip size and the high frequency clock signal. The noise source can also be removed to prevent operation errors and improve performance. Therefore, it is more effective when high speed is not required and it is used to send and receive serial data with a small amount of information.
