- 1is a computer system mainly designed to perform a specific task such as accessing, processing, store and controlling data in an electronics-based system.embedded system
- 2components of an embedded systemHardware
Software - 3Hardware ComponentsPower Supply – battery or external source
Processor – controls electrical and mechanical functions
Memory – stores hardware instructions
Timers – measure time intervals or elapsed time
Communication Ports – used to communicate with other types of embedded systems (UART, USB, Ethernet)
Input and Output – Examples of input are switch and keypad while examples of output are LEDs and LCDs.
Application-Specific Integrated Circuits (ASIC) – integrated circuits customized for a particular use - 4Software Componentsassembler, emulator, debugger, compiler
- 5Software CharacteristicsSingle-functioned

It must be based on a microcontroller or microprocessor.
It must require a memory, as its software generally inserts in ROM. It does not require any secondary memories in the PC.
It must have connected peripherals to attach input & output devices. - 6It executes a particular operation in a consistent manner.Single-functioned
- 7It has limitations on design metrics. A design metric is a measure of an execution features like size, power, cost and also performanceTightly constrained
- 8It must perform fast enough and consume less power to increase battery life.Real time
- 9It should constantly react to changes in the system and also calculate particular results in real time without any delayReactive
