A quick look at some Embedded Operating Systems
Real Time Operating Systems Real time operating systems are designed for real time applications that need to accomplish a certain tasks with as little OS overhead as possible. Tasks like reading the sensors and displaying data. You could write an infinite while loop to accomplish that but things will get complicated once you have multiple tasks. RTOS provide users with a task scheduler and several methods for synchronizing tasks and inter-task communication, as well as other stuff, not necessarily related to tasks....
