Illustrated Blog on Embedded Software Architecture
I found the inspiration for this article while working on a consultancy job: Priority inversion. In computer science, priority inversion is a (potential) problematic scenario in scheduling in which a high priority task is indirectly preempted by a medium priority task effectively inverting the relative priorities of the two tasks. (http://en.wikipedia.org/wiki/Priority_inversion) To put it more […]
Let us start with an interesting quote from the FreeRTOS web site: Binary semaphores are used for both mutual exclusion and synchronisation purposes. The quote clearly makes a distinction between the two use cases we saw in part 1: mutual exclusion: how to serialize access to shared data, and synchronization: how does a producer notify […]
