Lockheed Martin Selects Spectrum’s SDR-3000 for Software Communications Architecture Enabled Waveform Development

Burnaby, B.C., Canada — July 10, 2006 — Spectrum Signal Processing Inc. today announced an agreement with Lockheed Martin Corporation (NYSE: LMT) for its flexComm™ SDR-3000 software defined radio platform. Lockheed Martin will use the SDR-3000 for waveform development in a Software Communications Architecture (SCA) environment.

“Lockheed chose Spectrum for its leadership position in commercial-off-the-shelf SCA-enabled reconfigurable processing solutions,” said Russ Johnson, Principle Research Scientist at Lockheed Martin Integrated Systems and Solutions. “By selecting a Spectrum solution, I expect to advance my team’s knowledge of the SCA and SCA-enabled waveform development and accelerate Lockheed’s efforts under its next generation communications programs.”

“The SDR-3000 is an integrated subsystem that incorporates a range of software components from a number of leading vendors in the software defined radio marketplace,” said Pascal Spothelfer, Spectrum’s President and CEO. “This allows the SDR-3000 to provide all the hardware, software and design tools necessary for waveform development in an SCA environment to allow customers such as Lockheed to begin development work immediately thereby reducing their development time and risk.”

The SDR-3000 is a heterogeneous processing platform incorporating Xilinx® field programmable gate arrays, IBM and Freescale™ PowerPC® processors and Texas Instruments’ digital signal processors. It also includes Harris Corporation’s SCA Core Framework, VxWorks® real-time operating system by Wind River® and Spectrum’s quicComm™ hardware abstraction layer, which facilitates algorithm partitioning and programming with a real-time operating system. The SCA is an open architecture developed by the U.S. Department of Defense for its Joint Tactical Radio System program.
