QUALCOMM is using Green Hills' MULTI Development Environment and C compiler to develop software that will be embedded in Globalstar's wireless fixed-site satellite phones. The software, which runs on an Intel 386EX processor, provides overall control for the phone. It also implements the user interface, manages the CDMA-like physical layer ASIC, and performs call set up and tear down.

Green Hills' MULTI Development Environment and C compiler automates every aspect of the 386EX software development process. Featuring a window-oriented editor and a source-level debugger with support for process-and system-level debug, MULTI also includes a run-time error checker, application profiler, and both project and version control.

"The MULTI toolkit," noted Dennis Velte, QUALCOMM Project Manager for Globalstar User Terminal Software, "has been invaluable for helping us keep our software development team on schedule." "Particularly useful," added Velte, "is MULTI's process-level debug support, which made it easy for us to integrate the MULTI software with the handheld unit's real-time multitasking kernel."

MULTI is also tightly integrated with Green Hills' optimizing C compiler, which incorporates a host of innovative local and global optimizations. "These optimizations," remarked Green Hills President Dan O'Dowd, "are essential for developing the fast, compact code needed for small-form-factor embedded systems like the Globalstar hand-held phones."

Globalstar is a LEO satellite-based digital telecommunications system that will offer wireless telephone and other telecommunications services worldwide beginning in 1998. Globalstar will provide low-cost, high-quality telephony and other digital telecommunications services such as data transmission, paging, facsimile, and position location to areas currently underserved or not served by existing wireline and cellular telecommunications systems.

Globalstar service will be delivered through a 48-satellite LEO constellation that provides wireless telephone service in virtually every populated area of the world where the service is authorized by local telecommunications regulatory authorities. Globalstar will begin launching satellites in the second half of 1997 and will commence initial commercial operations via a 25-satellite constellation in 1998. Full 48-satellite coverage will be achieved in the first half of 1999.

Based in San Jose, California, Globalstar is a limited partnership led by Loral Space and Communications Ltd., of New York City. Along with co-founder, QUALCOMM Incorporated of San Diego, California, the partnership includes ten of the world's leading telecommuncations service providers and equipment manufacturers.
