Though there are good reasons to use a real-time operating system (RTOS) in some applications, this decision also creates a number of problems for embedded software developers. An RTOS adds excess complexity when the application is not well suited to being coded as a set of tasks that can preempt each other. This course examines RTOS tradeoffs and a set of alternative approaches to multitasking that do not employ a preemptive scheduler.
