Santa Barbara, CA. December 11, 2000 - Green Hills Software today announced that its MULTI IDE and the ThreadX® Real-Time Operating System (RTOS) have been selected by Pulmonetic Systems to develop graphics monitor software for its entire line of LTV™ Ventilators. The software will run on an ARM7TDMI processor under the ThreadX RTOS.

The LTM™ Graphics Monitor is a flat, portable monitor that provides an enhanced view of patient respiratory conditions through full color waveforms, loops, trends, and summary screens. The Graphics Monitor also provides connectivity to an array of peripherals like printers, modems, and patient data systems.

"We are extremely pleased Pulmonetic Systems has selected the ThreadX RTOS and Green Hills' MULTI IDE for its LTV™ Ventilator Graphics Monitor," said John Carbone, vice president of marketing at Green Hills Software. "The royalty-free ThreadX RTOS keeps costs down, while MULTI 2000 reduces system software development time and harnesses the full processing power of the ARM core."

"The bundling of ThreadX RTOS with the Green Hills MULTI IDE and its support for the ARM7TDMI processor was exactly what we needed," said David Boyle, manager of new product engineering at Pulmonetic Systems. "We were up and running on an evaluation platform in one day, and Green Hills' field application support was fantastic!"

The ThreadX RTOS is the most technically advanced real-time multitasking solution on the market today. Combining a picokernel design with fast timers and a high-speed preemption-threshold mechanism, ThreadX features a context switching time of less than two microseconds on a 40-MHz PowerPC 860 processor. The ThreadX picokernel is also memory stingy, requiring just 5 kbytes for a minimum footprint.

The MULTI 2000 IDE automates all aspects of software development for ARM processors running ThreadX, including the ARM7™, ARM7TDMI™, ARM7500FE™, ARM9E, and StrongARM® processors. Featuring an integrated programming editor, source-level debugger, graphical program builder, and run-time error checker, MULTI 2000 also includes a version control system, instruction set simulator, performance profiler, and real-time EventAnalyzer™.

ThreadX support is integrated directly into MULTI, enabling it to provide comprehensive task- and kernel-aware debugging. The new ThreadX-aware MULTI IDE can display multiple tasks ("threads") graphically, including the thread roster, system objects, stack usage, semaphore usage and status, and a variety of other thread- and system-specific information. This capability enables embedded developers to identify thread-specific bugs by setting either system- or thread-specific breakpoints.

MULTI's C/C++ compiler takes full advantage of ARM's architecture extensions, which enable designers to achieve significant reductions in code size without compromising performance. To help embedded systems programmers maximize performance and efficiency and make size/speed tradeoffs, the MULTI development environment provides a run-time execution profiler called CodeBalance™. CodeBalance lets users trade off reduced code size for increased performance with an easy-to-use GUI. The user can select limits for performance or code-size, and CodeBalance automatically optimizes the other until the selected limit is reached.
