"MULTI's integrated debug, program build, profiling, and version control facilities streamline the development of complex multiprocessor software for Mercury systems based on the RACE++ architecture and PowerPC microprocessors," said John Carbone, vice president of marketing at Green Hills Software. "At the same time, our optimizing compilers, which implement the AltiVec extensions to the C language, make it easier for programmers to harness the PowerPC's superscalar and vector processing facilities without having to program in assembly language."

"Integrated development environments for embedded real-time systems have become more powerful, and MULTI is the acknowledged leader," said Rich Jaenicke, director of product marketing at Mercury. "We chose MULTI for its powerful user interface, highly-integrated toolset, and extensibility to multiprocessor software development. Offering MULTI to Mercury software developers is the first step in Mercury's plan to provide best-of-breed mainstream software for our RACE++ high-performance embedded computer systems."

Mercury Computer Systems provides high-performance PCI and VME multiprocessing systems for digital signal and image processing applications based on the RACEway Interlink Standard. The RACEway standard (RACEway Interlink ANSI/VITA 5-1994), originally developed by Mercury, transforms the PCI and VMEbus from single-transaction buses into scalable, real-time, switched fabrics that are ideal for multiprocessing applications scaling from several to hundreds of processors. The RACE++ architecture, also developed by Mercury, is a second-generation architecture that extends the aggregate bandwidth of RACE® crossbar switches from 480 Mbyte/sec to 1 Gbyte/sec.

The MULTI 2000 IDE, available for Windows NT and Solaris hosts, automates all aspects of software development for PowerPC processors, including those equipped with the Altivec extensions. Featuring a window-oriented editor, source-level debugger, graphical program builder, and run-time error checker, MULTI 2000 also includes a version control system, instruction set simulators, performance profiler, and real-time EventAnalyzer™. MULTI also features the industry's most advanced PowerPC 7400 C/C++ optimizing compiler, which enables programmers to take full advantage of the processor's dual-issue and AltiVec vector processing capabilities without programming in assembly language.

The heart of the MULTI environment is a source-level incremental debugger, which features process- and system-level debug capability. The debugger supports mixed assembly and high-level language formats, includes a language-sensitive expression evaluator, provides a separate debug window for each process, and provides special support for C++ including a Class Browser, object display and template debug capability.

The MULTI 2000 debugger is fully RTOS aware, which enables designers to debug and tune their applications at a task level. The debugger also supports run-mode debugging, which enhances the debug process by enabling programmers to halt and debug tasks while the rest of the tasks continue to run.
