RTOS supports new microcontrollers
ThreadX is Express Logic's small, fast, royalty-free RTOS for demanding real-time applications.
Express Logic's ThreadX RTOS and NetX TCP/IP networking stack now support Luminary Micro's new Stellaris LM3S1000 series and LM3S8000 series ARM Cortex-M3-based microcontrollers (MCUs) ThreadX and NetX for the new Stellaris devices are designed for use with the ARM/Keil RealView IDE from ARM

RTOS gains development support
Express Logic has integrated its ThreadX RTOS into the Wind River Workbench 2.3 integrated development environment. Wind River Workbench.
The additions to the Stellaris microcontroller family offer new control and connectivity combinations for the ARM Cortex-M3 architecture.
The new Stellaris LM3S1000 series features enhanced memory and I/O options and the Stellaris LM3S8000 series provides the combination of 10/100 Ethernet MAC+PHY and up to three controller area network (CAN) interfaces on-chip.
Most new Stellaris family members are optimised for low-power applications using a battery-backed hibernation module with a real-time clock and 256byte of dedicated nonvolatile memory.

RTOS is ported to MIPS cores
The ThreadX RTOS is now available for the MIPS32 24K and 4KE processor core families.
RTOS supports deeply embedded ARMs
Express Logic's ThreadX RTOS now supports the ARM CortexTM-M3 microprocessor.
A free evaluation version of ThreadX and a demonstration program in source code form are available for Luminary Micro's Stellaris LM3S1968 and LM3S8962 Evaluation Kits.
The demonstration program consists of a simple multi-threaded application that uses features of ThreadX including message passing, thread creation and scheduling.
The entire application, including the ThreadX RTOS, requires less than 7Kbyte of flash and less than 4Kbyte of SRAM.
Users can modify the demonstration or write a completely new ThreadX application up to the evaluation version's limits, which consist of ten threads, one instantiation of each type of memory pool, and a maximum of two instantiations for each of the other ThreadX objects.
The demo application is provided in C source code form, is fully integrated with the LM3S1968 and LM3S8962 evaluation boards, and intended for use with the ARM/Keil RealView tools.
Jean Anne Booth, Chief Marketing Officer of Luminary Micro said "ThreadX presents a small memory footprint with an easy to use, rich set of system services such as threads, message queues, counting semaphores, and mutexes".
"The evaluation version and demonstration available for our new Stellaris evaluation kits offers a convenient introduction to the capabilities of ThreadX.
"We are pleased to extend ThreadX RTOS support for Luminary Micro's Stellaris family of Cortex-M3-based microcontrollers, including the 34 new microcontrollers announced today", commented John Carbone, Vice President of Marketing of Express Logic.
"Our NetX TCP/IP stack provide real-time networking capabilities in a small, efficient package, which is ideal for the new Stellaris MCUs featuring integrated 10/100 Ethernet MAC/PHY support ".
