Abstract
전원전압사양이 다른 반도체 집적회로장치가 혼재하는 시스템이나 여러개의 전원전압사양에 대응한 시스템을 구성하는 경우에 이용해서 유효한 기술로써, 전원전압사양이 다른 반도체 집적회로장치를 조합시켜서 시스템을 구성하는 경우에 대규모인 외부회로를 마련하는 일없이 저코스트로 시스템을 구성하기 위해 신호 또는 데이타의 처리를 실행하는 데이타 프로세서에 여러개의 레벨중 어느것인가로 신호를 입출력 가능한 입출력회로를 마련함과 동시에, 주변장치에는 데이타 프로세서로 부터의 지시신호에 대해서 응답신호로 출력하는 수단을 마련하고, 데이타 프로세서와 주변장치간에는 응답신호를 받아서 입출력회로에 대해서 그 응답신호에 대응한 전환신호를 부여하는 수단을 마련하는 구성으로 한다. 이러한 신호처리장치를 이용하는 것에 의해, 저코스트로 전원전압사양이 다른 장치를 조합시킨 시스템을 구성할 수 있음과 동시에, 전원전압사양마다 장치를 설계할 필요가 없게 되어 저코스트로를 도모할 수 있다.This technology is effective when a system in which semiconductor integrated circuit devices having different power supply voltage specifications are mixed or a system corresponding to several power supply voltage specifications is effective. The system is constructed by combining semiconductor integrated circuit devices having different power supply voltage specifications. In this case, a peripheral device is provided with an input / output circuit capable of inputting / outputting signals at any of several levels in a data processor that performs signal or data processing to construct a low cost system without providing a large external circuit. And a means for outputting a response signal from the data processor as a response signal, and a means for receiving a response signal between the data processor and the peripheral device and providing a switching signal corresponding to the response signal to the input / output circuit. It is done. By using such a signal processing device, a system in which a device having different power supply voltage specifications is combined with a low cost can be configured, and the device need not be designed for each power supply voltage specification, thereby achieving a low cost. .
