Santa Barbara, CA. August 6, 2001 -- Green Hills Software today announced the availability of version 3.0 of the MULTI® 2000 Integrated Development Environment for the ARM® family of microprocessor cores. Version 3.0 offers a number of new debug, compiler, and simulation enhancements that streamline software development for ARM core-based systems, including real-time trace support, run-mode and freeze-mode debugging, and both instruction set and cycle-count accurate simulation. The MULTI IDE, together with Green Hills' family of optimizing C, C++, and EC++ compilers, automates all aspects of embedded software development for the ARM7™, the ARM9™, the ARM9E™ and the ARM10™ processor families, along with the ARM architecture-compliant Intel® XScale™ microarchitecture.

"Version 3.0 adds several advanced debug and simulation features making it easier for designers to develop ultra-reliable code under real-world conditions," said John Carbone, vice president of marketing for Green Hills. "We've also beefed up our compilers for ARM cores, which together with MULTI's CodeBalance® optimizing profiler, enables designers to achieve maximum performance and code efficiency."

"Integrated development environments like MULTI are essential for developing sophisticated programs for high-performance ARM microprocessor cores in a timely fashion," said Rod Crawford, director, Third-Party Software, ARM. "Advanced optimizing compilers like Green Hills' help keep memory costs down while harnessing the full processing power of the industry-leading ARM architecture."

MULTI provides a uniform set of capabilities for software development using Windows 95/98, Windows NT, and Unix host platforms. The MULTI IDE features a window-oriented editor, source-level debugger, graphical program builder, run-time error checker, version control system, performance profiler, optimizing the ARM Thumb® profiler (CodeBalance®), and real-time RTOS EventAnalyzer. MULTI also features instruction set (SimARM) and cycle-count accurate (the ARMulator® software) simulators that allow programmers to develop and test code on a PC or workstation without the need for the target hardware.

The MULTI 2000 debugger is RTOS aware, enabling designers working with popular RTOSes like ThreadX to debug their applications and monitor OS resources, buffers, queues, and streams at task level. The MULTI debugger supports freeze mode and run-mode debugging, which enables programmers to perform debug functions and inspect processor/system resources with either the entire system, or individual tasks halted. The MULTI debugger also supports ARM's Embedded Trace Macrocell™ technology for real-time trace, which enables programmers to acquire target data and program flow information as the program executes without having to halt the processor.

MULTI supports a variety of host/target connectivity and debug options, including the ARM EmbeddedICE® technology, the ARM Multi-ICE® technology, the Angel ROM Monitor, Agilent's Emulator Probe, EPI's JEENI® and Macraigor's OCDemon.
