In addition to the standard feature set supported by most real-time kernels, the Abassi RTOS can be configured with many features unmatched in the industry. These features add robustness and code savings, and include:
Abassi supports major ARM development tools, including IAR (with multithread-safe library protection), Atollic (with multithread-safe library protection) and ARM/Keil.
Download an evaluation version of the RTOS for your build environment. Demonstrations are available for multiple evaluation platforms.
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.
