Abstract

본 발명은 카오디오의 처리속도 조절장치에 관한 것으로서 특히, 카오디오의 마이컴(2)에 클럭펄스를 발생시켜 주는 발진기(1)의 출력주파수를 변경시켜 주기 위한 키입력부(3)와; 상기 키입력부(3)의 키신호를 입력받아 카오디오내의 마이컴(2)을 리세트시키고 변화된 발진주파수의 코드값을 입력시켜 줌과 동시에 상기 발진기(1)가 변경된 클럭주파수를 발생시키도록 하는 제어용 마이컴(4)을 기존의 카오디오 시스템에 부가시켜 주므로서 카오디오 마이컴(2)의 처리속도를 작동모드에 따라 변경시켜 줄 수 있어 카오디오내의 마이컴이나 발진기를 교체시키지 않고도 각각의 작동모드에 따른 데이타를 최적의 상태에서 처리할 수 있어 제품의 신뢰도를 대폭 향상시킬 수 있는 것이다.The present invention relates to a processing speed control device for a car audio, and more particularly, a key input unit (3) for changing an output frequency of an oscillator (1) for generating a clock pulse in a car audio microcomputer (2); Receives a key signal from the key input section 3, resets the microcomputer (2) in the car audio and inputs the code value of the changed oscillation frequency and the oscillator (1) for generating a changed clock frequency By adding the microcomputer (4) to the existing car audio system, the processing speed of the car audio microcomputer (2) can be changed according to the operation mode, and according to each operation mode without replacing the microcomputer or oscillator in the car audio. The data can be processed optimally, which greatly improves the reliability of the product.
