一、微电子系统与专用电路(ASIC)超大规模集成是一种能力.其进一步发展取决于应用.围绕微处理器和存储器构成微电子系统及以某一应用为目的专用电路,是最重要的应用.传统的电子产品如电视机电路,手表电路等已趋向饱和,而传统非电子产品的电子化却方兴未艾,品种繁多.这种微电子系统的典型即是信息处理系统.典型的信息处理系统由输入信号转换(即非电能量转换为电能量)、信号处理(如放大、调制、滤波、计算等)及信号输出(如存储、显示、执行、发射等)三部分组成.由于信号处理用的微处理器十分成熟,故微电子系统和专用电路发展的主要关键是输入输出传感器的开发,即接口转换功能的研究.
I. Microelectronic Systems and Application-Specific Circuits (ASICs) Very large scale integration is a capability whose further development depends on the application. The most important is the formation of microelectronic systems and dedicated circuits for a specific application around microprocessors and memories Applications. Traditional electronic products such as television circuits, watch circuits, etc. have tended to be saturated, while the traditional electronic products are not yet in the electronization of a wide variety of microelectronic systems typical is the information processing system. Typical information processing system The signal processing (such as amplification, modulation, filtering, calculation, etc.) and the signal output (such as storage, display, execution, transmission, etc.) consists of three parts of the input signal conversion (ie, non-electrical energy converted to electrical energy) Microprocessor is very mature, so the main key to the development of microelectronic systems and dedicated circuits is the development of input and output sensors, that is, the study of the interface conversion function.
