mAbassi SMP RTOS for Cortex-A9

Multicore in than 6 kilobytes.

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...

Development Tool Choices

Abassi supports major ARM development tools, including ARM Design Studio 5, Xilinx SDK, Atollic TrueSTUDIO and Code Composer Studio.

Memory Requirements

Don't settle for half a RTOS! Even with all features enabled, Abassi still consumes less memory than the minimum configuration of most kernels. And you get advanced priority inheritance, asymmetric round-robin scheduling, starvation protection, and much more. Or, if memory footprint is paramount, Abassi scales to a minimum size that can't be matched.
