RTOS

The widely deployed CMX-RTX™ RTOS is a truly preemptive, multi-tasking RTOS offering one of the smallest footprints, fastest context switching and lowest interrupt latency times available on the market today. RTOS functionality provided in CMX-RTX includes task, message, queue, system, event, memory, resource, semaphore and timer management. CMX-RTX includes an intuitive Windows GUI that simplifies RTOS configuration.

Processor Families Supported: Kinetis, Power Architecture, ColdFire, i.MX, DragonFire, Flexis QE128, HC12, HCS12, HCS12X, 68HC11, 68HC12, 68HCS12, 68K, 683XX, CPU32 and DSP563XX.

The CMX-Tiny+™ real time multi-tasking operating system is a very “lean and mean” kernel for those processors that have a small amount of RAM embedded on the processor’s silicon (minimum of 512 bytes and higher.) This unique RTOS, based on a scaled down version of the popular CMX-RTX, retains most of the power of CMX-RTX as well as the more frequently used functions. ROM requirements are approximately 1K minimum to 3K maximum.

Processor Families Supported: Kinetis, Flexis QE128 (HCS08 and ColdFire V1) and 68HC08.
