An embedded system is a microcontroller or microprocessor based system which is designed to perform a specific task. For example, a fire alarm is an embedded system; it will sense only smoke.
An embedded system is a device with a computer designed for a specific purpose. To achieve that, the device needs an operating system that can respond fast and is prepared to keep working in any event. That is why we cannot rely on a general-use os, but an embedded operating system.
Partitioning is the activity of assigning cores to run specific operating systems. Multitasking and partitioning derive performance benefits from multicore processors. For embedded applications, partitioning is a key technique that can lead to substantial improvements in performance or reductions in cost.
