Maybe FreeRTOS is what you're looking for?  I note that it has a 
standardized interface for "Queues, binary semaphores, counting 
semaphores, recursive semaphores and mutexes for communication and 
synchronisation between tasks, or between tasks and interrupt." which is 
theoretically identical across the 23 microcontroller platforms that 
FreeRTOS works on.

The LuminaryMicro line of Cortex-M3 chips is the ARM setup I'm most 
familiar with, and while they can also run FreeRTOS, they also have some 
impressive brushless/sensorless motor control applications that take 
advantage of the deterministic nature of their nested vector interrupt 
controller.
