Abstract
본 발명의 데이타 전송장치는, 외부에서 인가되는 클럭 신호의 천이상태 또는 레벨을 검출하기 위한 천이감지 회로부와, 상기 천이 감지 회로부의 출력에 따라 데이타를 선입선출래치에 쓰거나, 상기 선입선출래치에 쓰여진 데이타를 읽어들이도록 제어하기 위한 제어기와, 상기 제어기의 제어신호에 따라 연속해서 읽거나 쓸수 있는 래치의 갯수를 나타내기 위한 상태 레지스터와, 상기 제어기의 제어신호에 따라 외부의 라이트 신호를 저장하거나 저장한 데이타를 외부에 리드 데이타로 내보내기 위한 선입선출래치를 포함하여 구성되며, 선입선출 래치에 연속 쓰기 동작 및 연속 읽기 동작시 클록신호의 천이상태를 이용하여 각각의 쓰기 동작 및 읽기 동작을 구분함으로써 데이타 처리시간을 단축시킬 수 있는 효과가 있다.The data transfer apparatus of the present invention includes a transition detection circuit section for detecting a transition state or a level of a clock signal applied from the outside, and a control circuit for writing data to the first-in-first-out latch in accordance with the output of the transition detection circuit section, A status register for indicating the number of latches that can be continuously read or written according to a control signal of the controller; and a status register for storing or storing an external write signal in accordance with the control signal of the controller And a first-in first-out latch for externally outputting one data to the read data. In the first-in first-out latch, the write operation and the read operation are distinguished by using the transition state of the clock signal in the continuous write operation and the continuous read operation, The processing time can be shortened.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.
제5도는 본 발명에 의한 데이타 전송장치로서, 호스트 프로세서와 주변장치간의 데이타 전송을 위한 연결을 도시한 것이며, 제6도는 제5도 주변장치 내부의 선입선출버퍼부의 제1실시예의 구성을 도시한 것이며, 제7도는 제5도의 호스트 프로세서가 제6도의 주변장치의 선입선출버퍼부중 선입선출버퍼에 연속적으로 데이타를 쓸때의 타이밍을 도시한 것이다.FIG. 5 is a data transmission apparatus according to the present invention, which shows a connection for data transmission between a host processor and a peripheral device. FIG. 6 shows a configuration of a first-in first- FIG. 7 shows the timing when the host processor of FIG. 5 continuously writes data to the first-in first-out buffer sub-first-in-first-out buffer of the peripheral device of FIG.
