Jacksonville, FL and Oslo, Norway - January 7, 2010 - CMX Systems today announced the availability of its widely deployed CMX-RTX™ and CMX-Tiny+™ RTOSes for Energy Micro’s ultra low energy 32-bit EFM®32 Gecko microcontroller family based on the ARM Cortex-M3 Microcontroller Core.

“CMX is pleased to expand its embedded offerings by introducing CMX-RTX and CMX-Tiny+ support for Energy Micros family of energy friendly microcontrollers. CMX-RTX and CMX-Tiny+ provides a truly preemptive, multi-tasking operating system for accelerating the development capabilities of designers who wish to take advantage of the EFM®32 Family’s unique capabilities.” stated Chuck Behrmann, CEO of CMX Systems. “With its broad array of kernel services and extremely small footprint, CMX-RTX and CMX-Tiny+ allow faster application development and efficient hardware utilization for Energy Micro based designs.”

“Building a software eco-system around our microcontrollers that makes it easy to create great energy efficient products is one of our key aims. The CMX-RTX and CMX-Tiny+ RTOSes have already proven themselves to be highly effective in the Cortex-M3 architecture at the heart of our EFM32 product so CMX’s support is very welcome.” said Stig Olsen, Software Manager at Energy Micro.

The CMX-RTX RTOS supports most 8-bit, 16-bit, 32-bit processors and DSP’s and offers one of the smallest footprints, fastest context switch times, and lowest interrupt latency periods of any commercial RTOS available. RTOS functionality provided in CMX-RTX includes support for: tasks, messages, queues, system, events, memory, resource, semaphores, timers, interrupts and optional kernel aware debugging. Flash requirements are approximately 1.5K minimum to 4.5K maximum.

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. Flash requirements are approximately 1K minimum to 3K maximum.

The CMX-RTX and CMX-Tiny+ also feature full source code, no royalties, and free technical support and updates with every purchase.
