应用特定集成电路(ASIC)目前已广泛用于为美国防部研制的新型电子系统的逻辑电路中。从导弹、雷达到战斗机都用到ASIC芯片。美国防部的新型电子系统中近80％的非存储微电路元件都是ASIC。 1 ASIC的分类标有“ASIC”的几种产品已经在市场上出现,但是真正ASIC的定义还不明确。许多专家认为只有较高级的ASIC产品才能享有此名。ASIC领域的最高级产品是“全定制”芯片,它是专为高效率地完成特定任务而定做的。次一级产品是“半定制”芯片,它有几种不同类
Application-specific integrated circuits (ASICs) are now widely used in logic circuits for new electronic systems developed by the US Department of Defense. From missiles, radars to fighter jets, ASIC chips are used. Nearly 80% of the non-storage microcircuitry components in the new electronic systems of the US Department of Defense are ASICs. 1 Classification of ASICs Several products labeled “ASIC” have appeared on the market, but the definition of real ASICs is not yet clear. Many experts believe that only higher-level ASIC products can enjoy this name. The top-level product in the ASIC space is a “full-custom” chip that is tailor-made for high-efficiency tasks. The next-level product is a “semi-custom” chip, which has several different classes.
