In a classic scenario of priority inversion, a binary semaphore is named 'PRNT' to symbolize that it is being used to regulate the access of tasks to a printer. It is initialized with a count of one ...

Designing embedded real-time computer systems. Types of real-time systems, including foreground/background, non-preemptive multitasking, and priority-based pre-emptive multitasking systems. Soft vs.

The use of a real-time multitasking kernel simplifies the design process of embedded software, but the kernel requires some portion of system's resources. This paper describes results of research work ...

David Kalinsky of OSE Systems explains how hardware memoryprotection on processors can be exploited to improve RTOSreliability. Highly reliable embedded systems must be robust with respect to avast ...
