Abstract
직렬 통신 인터페이스(Serial Communication Interface), 회로에 관한 것으로, 특히 MPSC(Multi-protocol Serkal Cmtroller)를 이용한 직렬 통신 제어기에 관한 것이다.Serial communication interface (Serial Communication Interface), and a circuit, in particular relates to a serial communication controller using a multi-protocol Serkal Cmtroller (MPSC).
상기 MPSC를 이용한 통신 제어기는 PC/AT 시스템에 접속되어 입출력 신호를 접속하는 PC/AT 버스로부터 출력되는 어드레스와 콘트롤 신호를 디코딩하여 제어신호를 출력하는 CTL-L과, 상기 PC/AT 버스 입출력되는 데이터를 버퍼링하는 버퍼를 가지고 있다. 그리고 상기 CTL-L과 버퍼에는 A, B 두 개의 송수신 채널을 가지고 있으며, 상기 CTL-L의 출력 제어에 의해 A 채널의 송수신 DMA 요구신호와 B채널의 송수신 요구신호를 발생함과 동시에 상기 버퍼를 통한 데이터를 A채널/B채널로 송수신하는 MPSC가 접속 구성된다.The communication controller using the MPSC is connected to a PC / AT system, the CTL-L to decode the address and the control signal output from the PC / AT bus to connect the input / output signal and output the control signal, and the PC / AT bus It has a buffer to buffer the data. In addition, the CTL-L and the buffer have two transmit and receive channels A and B. The output control of the CTL-L generates the transmit / receive DMA request signal of the A channel and the transmit / receive request signal of the B channel, and the buffer is simultaneously transmitted. An MPSC for transmitting and receiving data through the A / B channels is connected.
상기와 같이 MPSC를 이용한 통신 제어기는 2개의 직렬 통신 채널에서 DMA 요구신호를 발생함으로서, 직렬 통신을 보다 효율적으로 할 수 있다.As described above, the communication controller using the MPSC generates the DMA request signals in two serial communication channels, thereby making serial communication more efficient.
