CMX Systems announces CMX-RTX and CMX-TINY+, Real-Time Multi-Tasking Operating Systems support for Stellaris® Microcontrollers

RTX and TINY+ RTOS Optimized for Small Footprint and Multi-tasking Requirements of Popular Cortex™-M3-based Stellaris MCUs

Jacksonville, FL and Austin, TX - January 3, 2007– CMX Systems today announced the availability of CMX-RTX™ and CMX-Tiny+™ RTOS for Luminary Micro’s Stellaris microcontrollers based on the ARM® Cortex-M3 microcontroller core. Luminary Micro is ARM’s lead partner for the Cortex-M3 core and is the first company to bring ARM for $1.00 to embedded developers. The company currently offers a popular family of 19 Stellaris 32-bit microcontrollers at 8- and 16-bit prices.

“CMX is pleased to expand its microcontroller support by introducing CMX-RTX and CMX-Tiny+ support for the Stellaris Cortex-M3 family. CMX-RTX and CMX-Tiny+ provides a truly preemptive, multi-tasking operating system for accelerating development capabilities of designers using Stellaris microcontrollers ,” 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 easier hardware utilization for Stellaris developers.”

CMX-RTX RTOS supports most 8-bit, 16-bit, and 32-bit microcontrollers and DSPs. It offers the smallest footprint, the fastest context switch times, and the lowest interrupt latency periods of any commercial RTOS available today. 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 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.

“CMX Systems is a recognized leader in providing RTOS products for high-performance embedded microcontrollers,” said Jean Anne Booth, CMO of Luminary Micro. “The introduction of CMX-RTX and CMX-Tiny+ for the Stellaris Cortex-M3 family provides designers with expanded capability and flexibility for real-time applications using Stellaris microcontrollers.”

Both CMX-RTX and CMX-Tiny+ also integrate with the CMX-MicroNet™ 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.

CMX-RTX and CMX-Tiny+ are available from CMX Systems and its distributors listed at www.cmx.com . Contact CMX Systems at 904-880-1840 or email cmx@cmx.com. Luminary Micro’s Stellaris microcontrollers are available through their global sales channel (www.LuminaryMicro.com/sales)
