For the most part, Embedded system is based on a microcontroller that will usually perform one of several concrete operations, like playing music, grabbing photos, gathering samples from sensors etc.
A-Z Embedded encourages you to choose an Embedded system instead of a microprocessor when a determined number of tasks are required to be done by the product and not too many inputs are involved.
Embedded systems can also perform complex operations like:
- Implementing Network stack and connecting to the internet.
- Interfacing USB flash device ,SD card etc.
- performing a determined number of tasks by running RTOS (a small OS-like)
The advantages of an Embedded System is:
- a Low cost compared to Embedded Linux.
- Low power.
- The microcontroller is running only the product's software, and not dealing with other OS tasks in background.
