Large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when the semiconductor complex and communication technologies were being developed. The microprocessor is a VLSI device.
Prior to the introduction of VLSI technology, most ICs had a limited set of functions that they could perform. An electronic circuit may consist of a CPU, ROM, RAM and other glue logic. VLSI allows IC designers to add all this on a single chip.
The electronics industry has achieved phenomenal growth in recent decades, mainly due to rapid advances in large-scale integration technologies and systems design applications. With the advent of designs large-scale integration (VLSI), the number of applications of integrated circuits (IC) in high performance computing, controls, telecommunications, processing of electronic images and video consumption has increased at a much slower pace Quick.
Today's state-of-the-art technologies, such as high resolution and low bit rate video and cellular communications, provide end users with a marvelous amount of applications, processing power and portability. This trend is expected to grow rapidly, with very important implications in VLSI design and systems design.
