Abstract

본 발명은 두 개의 콘트롤러간의 데이타 전송 제어방법에 관한 것으로, 데이타를 전송받을 측의 처리속도에 맞추어 데이타를 전송할 수 있도록 한 콘트롤러간의 데이타 전송 제어방법에 관한 것이다. 두 개의 콘트롤러간의 데이타 전송에 있어서, 직렬데이타 전송시 서로의 데이타 처리능력이 다름으로, 상대측 콘트롤러의 즉 데이타를 전송받을 측의 처리능력을 감안한 데이타 전송 방법이 필요하다. 이에 본 발명에서는 두 개의 콘트롤러의 데이타 전송 제어에 있어서, 데이타 받는 측에서 출력되는 클럭신호에 맞추어 데이타를 전송하도록 하므로서, 데이타를 전송받는 측의 처리 능력에 알맞은 데이타 전송을 할 수 있도록 한 콘트롤러간의 데이타 전송 제어방법이다.The present invention relates to a method for controlling data transmission between two controllers, and more particularly, to a method for controlling data transmission between controllers so that data can be transmitted according to a processing speed of a receiving side. In the data transmission between two controllers, since data processing capability of each other is different in serial data transmission, a data transmission method considering the processing capability of the counterpart controller, that is, the data receiving side, is needed. Accordingly, in the present invention, in the data transmission control of two controllers, the data is transmitted in accordance with the clock signal output from the data receiving side, so that the data between the controllers can transmit data appropriate to the processing capability of the receiving side. Transmission control method.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 콘트롤러간의 데이타 전송 제어방법의 실시예로서 휴대용 정보단말기의 메인 콘트롤러와 입/출력 및 통신 콘트롤러와의 데이타 전송라인 구성을 보인 블럭도.1 is a block diagram showing a data transmission line configuration between a main controller and an input / output and communication controller of a portable information terminal as an embodiment of a method for controlling data transmission between controllers of the present invention.

제2도는 본 발명 콘트롤러간의 데이타 전송 제어방법의 실시예에 있어서, 메인 콘트롤러로부터 입/출력 및 통신 콘트롤러측으로의 데이타 전송시 출력되는 파형도.2 is a waveform diagram outputted during data transmission from a main controller to an input / output and a communication controller in an embodiment of a method for controlling data transfer between controllers of the present invention.

Claims (1)

두 개의 콘트롤러간의 데이타 전송 제어에 있어서, 어느 일측의 콘트롤러로부터 출력되는 비지신호를 검색하는 단계와, 상기 단계의 검색 결과에 따라 인터럽트신호를 출력하여 데이타 전송 준비를 하는 단계와, 데이타를 전송받을 측으로부터 출력되는 클럭신호를 인식하는 단계와, 상기 단계에서 인식된 클럭신호의 속도에 맞추어 데이타를 전송하는 단계로 이루어지는 것을 특징으로 하는 콘트롤러간의 데이타 전송 제어방법.In the data transfer control between two controllers, the method comprises: searching for busy signal output from one of the controllers, preparing an data transfer by outputting an interrupt signal according to the search result of the step, and receiving the data. And recognizing a clock signal output from the controller, and transmitting data in accordance with the speed of the clock signal recognized in the step. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
