Characteristics of an Embedded system

Learn some characteristics of an Embedded system.

1. Single functioned – Perform specialized operation and does the same task repeatedly.
2. Tightly constrained – It must be of a size to fit on a single chip and perform fast enough to process data in real time and consume minimum power.
3. Reactive and Real time – continuously react to changes in the system’s environment and must compute relevant results in real time.
4. Microprocessor based – an embedded system must be microprocessor or microcontroller based.
5. Memory – It must have a memory, embeds in ROM. But it does not need any secondary memory.
6. Connected – It is connected with peripheral devices to get/give input and output.
7. HW-SW systems – It is used for more features and flexibility. And hardware is used for performance and security.
