一、超大规模集成(VLSI)特点及能力1.集成度与计算能力自1959年世界上第一块半导体硅集成电路研制成功以来,集成电路以其极高的性能价格比,受到工业界及学术界极端的重视,实现了人类历史上最为迅速的技术发展.衡量一个集成电路技术进步的主要标志是集成度.所谓集成度是指每一个硅芯片上所集成的品体管的数目.集成度的提高使集成电路的功能增强,单位功能的成本降低,电路速度提高,功耗下降,可靠性提高.这些优点恰恰就是集成电路发明的驱动力,是分立元件组成的电路发展到集成电路的根本原因.数字集成电路的主要应用是数字信号处理.一般用信息吞吐率
First, the VLSI (VLSI) features and capabilities 1. Integration and computing power Since 1959 the world’s first successful development of semiconductor integrated circuits, integrated circuits with its high cost performance, by industry and academia Extreme attention has been given to the most rapid technological advancement in human history.A major measure of the technological advance of an integrated circuit is integration, which refers to the number of transistors integrated on each silicon chip. Improve the integrated circuit function enhancements, the unit cost of the function to reduce the circuit speed, power consumption decline, improve reliability.These are precisely the driving force of the invention of integrated circuits, is the discrete components of the circuit development to the basic integrated circuits The main application of digital integrated circuits is digital signal processing. General information throughput
