Abstract
본 발명은 2개의 마이크로 컴퓨터를 구비한 텔레비젼에 있어서 메모리 장치, 예컨대 디스플레이 RAM을 공유하여 데이터 처리 및 메모리 공간 사용상의 효율성을 높이도록 한 텔레비젼의 메모리 공유장치에 관한 것으로, 텔레비젼의 기본적인 동작제어를 위한 제1마이크로 컴퓨터(1)와 텔레텍스트 및 캡션신호를 처리하기 위한 제2마이크로 컴퓨터(2), 상기 제1마이크로 컴퓨터(1)의 데이터 입출력을 담당하는 제1I/O인터페이스(3), 상기 제2마이크로 컴퓨터(2)의 데이터 입출력을 담당하는 제2 I/O 인터페이스(4)를 구비한 텔레비젼 수상기에 있어서, 영상데이터를 저장하는 디스플레이 RAM(5), 상기 제1마이크로 컴퓨터(1)의 선택신호에 의해서는 상기 제 I/O 인터페이스(3)와, 상기 제2마이크로 컴퓨터(2)의 선택신호에 의해서는 상기 제2 I/O 인터페이스(4)와 각각 접속되는 멀티플렉서(6)를 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a memory sharing apparatus of a television in which a memory device, such as a display RAM, is shared to increase efficiency in data processing and memory space use in a television having two microcomputers. A second microcomputer 2 for processing teletext and caption signals with a first microcomputer 1, a first I / O interface 3 for data input and output of the first microcomputer 1, and the first microcomputer 1; In a television receiver having a second I / O interface 4 which is responsible for data input and output of a two-microcomputer 2, the display RAM 5 storing image data and the first microcomputer 1 are selected. The signal is in contact with the second I / O interface 3 and the second I / O interface 4 by the selection signal of the second microcomputer 2, respectively. And a multiplexer 6, which is characterized in that configured.
