现代电子产品的两个显著的时代特征是一“软”一“硬”。“软”指的是基于计算机CPU的软件编程技术,“硬”指的就是ASIC。ASIC是专用集成电路英文名称的缩写。 十年前,电子产品设计的基本思路是先选用通用的标准集成电路型号芯片(例如数字通用芯片74系列等等。这些芯片基本上都是小规模集成和中规模集成电路),再由这些芯片和其它元件构成更大的电路和电子系统。现在集成电路的制造工艺发生了巨大的变化,集成数以亿计的晶体管、几万门、几十万门电路的芯片已较为普遍。目前,这些芯片仍被笼统地称之为VLSI(超大规模集成电路)。VLSI通用芯片的发展并不
Two notable epochs of modern electronic products are “soft” and “hard.” “Soft” refers to the computer-based software programming technology, “hard” refers to the ASIC. ASIC is an acronym for the English name of an ASIC. Ten years ago, the basic idea of electronic product design was to first select a standard standard integrated circuit chip (such as the digital general purpose chip 74 series, etc. These chips are basically small-scale integrated and medium-scale integrated circuits) And other components form a larger circuit and electronic systems. Now integrated circuit manufacturing process has undergone tremendous changes, the integration of hundreds of millions of transistors, tens of thousands of gates, hundreds of thousands of circuit chips have become more common. At present, these chips are still generally referred to as VLSI (Very Large Scale Integration). VLSI general-purpose chip development is not
