WHAT ARE EMBEDDED SYSTEMS?

Embedded systems are combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function.

In some cases, embedded systems are part of a larger system or product, as in the case of an antilock braking system in a car. Contrast with general-purpose computer.

Embedded systems are the applications that fuel some of the microprocessors that play a hidden but crucial role in our everyday lives.

An embedded system consists of two components: a compact, ultra reliable operating system that controls the microprocessor inside a device, and the suite of applications that runs on the operating system.

VLSI is just about chip design, designing hardware, whereas embedded systems are a composite solution of creating software for a given hardware to deliver required functionality.
