- 2. What is anEmbedded System? An embedded system is some combination of computer hardware and software, either fixed in capability or programmable, that is specifically designed for a particular function. It is embedded as part of a complete device often including hardware and mechanical parts. Modern embedded systems are often based on microcontrollers (i.e. CPUs with integrated memory or peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more-complex systems.

Difference between Embeddedand General Purpose System Embedded System • Designed to do some specific set of tasks. • Not programmable by end user. • Low power consumption. • Fixed time constraints. • Task specific that’s why more economical. General Purpose System • Can perform multiple tasks. • Programmable by end user. • Generally high power consumption. • Does not have fixed time constraints. • Generally costly than task specific system.

Key Components ofEmbedded Systems Processors: • It is the central processing unit known as the heart of the embedded systems. • It is the hardware that executes the software and brings life to the embedded system. • Controls the activities of all the other circuits. Memory: • Used to store the software that the processor will run. • Also provides storage for data such as program variables, intermediate results, status information and any other data generated throughout the operation.
- 8. Processor • A processoris the heart of the Embedded System. • For an embedded system designer the knowledge of microprocessor and microcontroller is a must.

- 10. Microprocessor • A microprocessoris a single chip semi conductor device also which is a computer on chip, but not a complete computer. • Its CPU contains an ALU, a program counter, a stack pointer, some working register, a clock timing circuit and interrupt circuit on a single chip. • To make complete micro computer, one must add memory usually ROM and RAM, memory decoder, an oscillator and a number of serial and parallel ports.
