CMX-RTX RTOS supports most 8-bit, 16-bit, and 32-bit microcontrollers and DSPs. It offers a small footprint, fast context switch times, and the low interrupt latency periods. RTOS functionality provided in CMX-RTX includes support for: tasks, messages, queues, system, events, memory, resource, semaphores, timers, interrupts, and optional kernel aware debugging. ROM requirements are approximately 1.5K minimum to 4.5K maximum. The CMX-Tiny+ real-time multitasking operating system is a kernel for those processors that have a small amount of RAM embedded on the processor's silicon (minimum of 512 bytes and higher.) This RTOS, based on a scaled-down version of the 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.

Both CMX-RTX and CMX-Tiny+ integrate with the CMXMicroNet ™ TCP/IP stack for those applications requiring networking connectivity. CMX-RTX and CMX-Tiny+ also feature full source code, no royalties, and free technical support and updates with every purchase.
