  5. ^ "Why RTOS and What Is RTOS?". Retrieved 29 August 2014. What is FreeRTOS? … The size constraints, and dedicated end application nature, rarely warrant the use of a full RTOS implementation - or indeed make the use of a full RTOS implementation possible. FreeRTOS therefore provides the core real-time scheduling functions, inter-task communication, timing, and synchronisation primitives only. This means it is more accurately described as a real time kernel, or real time executive. …
