mAbassi SMP RTOS for Altera SoC

Multicore in than 6 kilobytes (details).

In addition to the standard features supported by all RTOS, the Abassi family has many features unmatched in the industry:


    1. Intelligent starvation protectionGuarantees fair access to CPU, via enhanced priority aging, even on heavily loaded systems.
    2. Priority inheritance, including dynamic trackingAutomatically adjusts for priority aging, timeouts, etc. and propagationBetween entangled mutex owners, to prevent deadlock.
    3. Adaptive priority ceilingTarget priority is self determined.
    4. Deadlock detectionReports recursive mutex dependencies anywhere in the execution chain.
    5. AsymmetricTimeslice adjustable at a per task level. Round Robin scheduling
    6. and more...
