Embedded system is the term used to any computing system that is used to perform a limited or specialized task. Unlike a general purpose computer that can perform a wide variety of tasks and is very complex, an embedded system is rather simplistic and does not have unnecessary hardware. ATMs, routers, calculators, and mobile phones are a few examples of devices that have embedded systems in them. On the other hand, VLSI stand for Very Large Scale Integration, which is a term used to describe the complexity of an integrated circuit by giving a generalized idea of how many transistors are within the circuit. Integrated circuits that contain thousands of transistors in a single package are classified as VLSI
