Version 4 is Now Available for Immediate Download - Including Support for Luminary Micro's Stellaris(TM) Family of ARM Cortex-M3(TM) Based Microcontrollers Version 4 Port and Demo Application Included in Luminary Micro's

Stellaris Development Kit and Available From

    BRISTOL, England, March 27 /PRNewswire/ -- The Bristol-based company
 announces today the immediate availability of ports supporting
 Luminary Micro's Stellaris(TM) family of microcontrollers, featuring the ARM
 Cortex-M3 microcontroller core. is a portable, open source,
 miniature Real Time Kernel for use in embedded applications. is
 free to download and royalty free for use even in commercial applications,
 subject to the license.
     The port for Stellaris microcontrollers is also included in
 Luminary Micro's Stellaris Development Kits, along with a pre-configured
 demonstration application showing the use of in small application
     "We are very pleased to be able to offer our embedded microcontroller
 customers access to this high quality open source RTOS," said Jean Anne Booth,
 Chief Marketing Officer of Luminary Micro. "We downloaded and used in the engineering development test environment during the
 development of our new Stellaris family of microcontrollers, and we found to be both easy to use and highly efficient in real embedded
 memory-constrained applications. Now that we have released the first of the
 Stellaris microcontrollers to the market, we anticipate that our customers
 will find to be as useful as we did." version 4 supports preemptive, cooperative, and co-routine
 execution. Co-routine execution is new with this release and is ideal for
 embedded systems with small RAM availability. Coroutines are prioritized,
 function co-operatively, share a stack with the task in which they run, and
 require very little RAM. This makes version 4 ideal for the first
 members of the Stellaris family of microcontrollers; both the LM3S101 and
 LM3S102 feature 8Kbytes of flash memory and 2K bytes of SRAM.
     "Based on their positive experiences using during silicon
 development, Luminary Micro contacted us about adding a port and
 demo application in their Stellaris Development Kit, and we were happy to
 oblige," said founder Richard Barry. "We have seen a marked
 increase of interest in ARM-based microcontrollers in general, and after
 working with early Stellaris family silicon, we think the availability of the
 first ARM Cortex-M3 microcontrollers will accelerate this trend." is gaining popularity with users on all continents for its
 easy accessibility and simplicity of use. Newly available and commercially
 backed development and support packages, along with ARM Cortex M3 support will
 further increase its appeal.

     About Luminary Micro, Inc.
     Founded in 2005, Luminary Micro, Inc. designs, markets and sells ARM
 Cortex-M3-based microcontrollers (MCUs). Privately held Austin, Texas-based
 Luminary Micro is ARM's lead partner for Cortex-M3, delivering the world's
 first silicon implementation of the Cortex-M3 core. Luminary Micro's
 introduction of the Stellaris(TM) family provides 32-bit performance for the
 same price as current 8- and 16-bit microcontroller designs. With entry-level
 pricing at $1.00 for an ARM-based MCU, Luminary Micro's Stellaris product line
 allows for standardization that eliminates future architectural upgrades or
 software tools changes. Contact the company at 512 279 8800 or email for more information.
