* Compact, ROMable real time operating system * Rapid task context switching * Fast interrupt response * Nested interrupts with priority ordering * Preemptive, priority based task scheduler * Timing support for delays, timeouts, periodic events * Time slicing option with adjustable slices * Message passing with configurable message length * Dynamic task creation and dynamic task priorities * Protection against task priority inversion

* System type - multithread, preemptive * Scheduler - maximum priority, fast context switch between threads, preemption may be blocked for specific part * Synchronization objects - mutex (nesting allowed), counting semaphore (may be signalled from ISR) * Timing control - timers, timeouts in semaphore waiting function, sleep function * Communication - ring buffers, effective implementation of queue, events * State machines - finite state machines support for coding behavior, unified events defined for commutication, active state machines manager that performs control over state machines * Memory management - memory pool, effective allocator, free of fragmentation issue * Debugging support - signalling events on chip pins (useful when tracking time dependencies and real time bugs), critical exceptions for unrecoverable bugs, deleted objects marking * Configuration - Many user configurable flags that affects compiled code of the system, User assigns processor resources that are used by the operating system
