Application specific integrated circuit

中文百科

特殊应用集成电路 Application-specific integrated circuit

(重定向自Application specific integrated circuit)

特殊应用集成电路英语:Application-specific integrated circuit,缩写:ASIC),是指依产品需求不同而客制化的特殊规格集成电路;相反地,非客制化的是应用特定标准产品(Application-specific standard product)集成电路。

特殊应用集成电路是由特定用户要求和特定电子系统的需要而设计、制造。由于单个专用集成电路芯片的生产成本很高,如果出货量较小,则采用特殊应用集成电路在经济上不太实惠。这种情况可以使用可编程逻辑器件(如现场可程序逻辑门数组)来作为目标硬件实现集成电路设计。此外,可编程逻辑器件具有用户可编程特性,因此适合于大规模芯片量产之前的原型机,来进行调试等工作。但是可编程逻辑器件在面积、速度方面的优化程度不如全定制的集成电路。

A tray of Application-specific integrated circuit (ASIC) chips.
Microscope photograph of a gate-array ASIC showing the predefined logic cells and custom interconnections. This particular design uses less than 20% of available logic gates.
Microscope photograph of custom ASIC (486 chipset) showing gate-based design on top and custom circuitry on bottom.

An application-specific integrated circuit (ASIC) /ˈsɪk/, is an integrated circuit (IC) customized for a particular use, rather than intended for general-purpose use. For example, a chip designed to run in a digital voice recorder or a high-efficiency Bitcoin miner is an ASIC. Application-specific standard products (ASSPs) are intermediate between ASICs and industry standard integrated circuits like the 7400 or the 4000 series.
