LSI
noun [ U ] electronics, computing specialized uk/ˌel.esˈaɪ/ us/ˌel.esˈaɪ/
大规模集成（large-scale integration的缩写）
abbreviation for large-scale integration: the process of putting thousands of transistors (= very small pieces of electronic equipment) on a single silicon chip (= a small piece of silicon that is used in computers, phones, etc.)
Computers built after 1972 are often called "fourth generation" computers, based on LSI (Large Scale Integration) of circuits—typically 500 or more components on a chip. 1972年之后制造的计算机通常被称为“第四代”计算机，基于LSI（大规模集成）电路——通常一个芯片上有500个或更多的组件。
LSI circuits approaching 10,000 transistors began to be produced around 1974.
- More examples
- Early LSI and VLSI devices (such as the microprocessors of the early 1970s) were mostly created by hand.
- A transmitter like this became feasible with the advent of LSI (large-scale integration).
- Circuits used to contain transistors numbered in the tens, but development lead to Large Scale Integration (LSI) (thousands), and VLSI (hundreds of thousands and beyond).
