MULTI and Rational Rose RealTime(TM) Make It Easy To Model, Develop,

and Deploy Complex Embedded Applications

Green Hills Software Inc., a leading supplier of embedded software solutions, today announced the integration of its MULTI(R) 2000 Integrated Development Environment (IDE) with Rational Rose RealTime(TM).

Together, MULTI and Rational Rose RealTime Unified Modeling Language (UML) tools greatly simplify the conceptualization, development and deployment of complex embedded applications for a wide range of microprocessors and real-time operating systems.

"The MULTI IDE and Rational Rose RealTime tools provide an excellent platform for graphical development and deployment of complex real-time embedded applications," said John Carbone, Green Hills' vice president of marketing. "The MULTI IDE makes it easy to debug applications developed using Rational Rose RealTime and generate optimized, error-free code that executes efficiently and reliably on the target system."

"Rational Rose RealTime facilitates a top-down approach to software design that makes it easy to conceptualize and structure complex applications," added David Abelow, director of alliance marketing for Rational Software "The MULTI IDE, together with Green Hills' optimizing compilers, make it easy for Rational Rose RealTime users to debug and optimize their applications for deployment on high-availability, and deeply embedded target systems."

Rational Rose RealTime is a comprehensive visual development environment that enables developers to design applications at a high level, greatly reducing the need to write in C and C++. Rational Rose RealTime provides a powerful combination of notation, processes, and tools to meet real-time challenges. Through the industry standard UML, real-time design constructs, code generation, and model execution, Rose RealTime addresses the complete project lifecycle, from early use case analysis, through design, implementation, and testing.

Rational Rose RealTime automatically generates C or C++ code to perform the functions that designers specify in their high-level diagrams. The MULTI IDE, together with Green Hills' compilers, makes it easy for designers to compile, download, and debug this code for execution on a target system. MULTI features a window-oriented editor, source-level debugger, graphical program builder, run-time error checker, version control system, and performance profiler. MULTI also features an instruction set simulator that allows programmers to develop and test PowerPC C/C++ code on a PC or workstation without the need for the target hardware.

The heart of the MULTI IDE is a source-level debugger that supports process- and system-level debug. The debugger provides a separate window for each process, supports mixed assembly and high-level language formats, and includes a language-sensitive expression evaluator. The MULTI 2000 debugger is also fully RTOS aware, which enables designers to debug and tune their applications at the task level. With the MULTI debugger, designers working with popular RTOSes like INTEGRITY(TM) and ThreadX(R) can start and stop tasks and monitor OS resources like buffers, queues, and streams. Programmers can set application breakpoints in either the Rational Rose RealTime UML model or generated C/C++ source code (within MULTI). These breakpoints facilitate synchronized debugging between Rational Rose RealTime and MULTI. When a breakpoint is encountered during execution, the application stops running on the target system. Programmers can then single-step the application from within the model view or source code view, synchronized through MULTI.

MULTI 2000, INTEGRITY, ThreadX, and the Rational Rose RealTime Adaptation Layer and Integration Layer, are available directly from Green Hills Software. MULTI integrated with Rose RealTime costs $1,900 to $2,900 per user. The Rose RealTime/MULTI Adaptation Layer costs $2,000 per user. All products are available immediately. Please contact Green Hills' sales office for product pricing and delivery. Rational Rose RealTime is available from Rational Software.
