Question

Embedded system software design using rtos

Answer 1

RTOS are Operating Systems (OS) which act in Real Time (RT). This means that RTOS have other purposes than general OS or embedded operating systems (EOS). Where the general OS have the goal to maximize the average throughput of tasks (data?), in RTOS the keyword is determinism. Tasks have to be dealt with in a certain deterministic amount of time. Violation of the specified timing constraints is (normally) considered catastrophic. Because of this strong difference, the implementations of RTOS differ significantly from other OS, although the general principles are the same.
