Environment to aid
mine detection development
Boeing has selected Green Hills Software's Multi integrated development environment for its long-term mine reconnaissance system (LMRS)
Multi will be used to develop the PowerPC-based data acquisition and image-processing software that detects and identifies mines at sea. The LMRS is a clandestine mine reconnaissance system that provides an early, rapid and accurate means of surveying potential mine fields. By employing unmanned underwater vehicles (UUVs), the LMRS is also capable of launch and recovery from SSN 688 and NSSN class submarines.

Environment provides full Eclipse support
Users of the Eclipse framework and its C/C++ development tools can now take advantage of the DSO capabilities of the Multi development environment and C/C++ compilers
One of the components of the LMRS is a torpedo-like acoustic sensor that acquires data, forms images and locates mines, while the second component is a submarine-based imaging system that performs final classification.
The software for the acoustic sensors runs on a Motorola PowerPC processor.
This software, developed using Green Hills Software's Multi, is written almost entirely in C++, using the PowerPC's Altivec instructions to process computer-intensive signals and image processing functions.
It is compiled using Multi's optimising C/C++ compiler, which takes full advantage of the Altivec SIMD (single instruction multiple data) parallel processing facilities.
Multi, together with Green Hills Software's family of optimising C, C++, EC++ and Ada95 compilers, automates all aspects of embedded software development for multiprocessor PowerPC systems.
Featuring a window-oriented editor, source-level debugger, graphical program builder and run-time error checker, Multi also includes a version control system, performance profiler, CodeBalance speed/size optimising profiler and real-time EventAnalyzer.
Additionally, Multi provides an instruction-set simulator that allows programmers to develop their PowerPC code on a Windows PC or Unix workstation without target hardware.
The Multi debugger is RTOS aware, enabling designers working with an RTOS to debug, monitor and tune their applications at the task level.
