Spectrum Signal Processing flexComm SDR-3000 Platform
Selected for Wideband Electronic Warfare Application

BURNABY, BRITISH COLUMBIA--(CCNMatthews - March 17, 2005) - Spectrum
Signal Processing Inc. (TSX:SSY)(NASDAQ:SSPI), today announced that its
flexComm SDR-3000 platform has been selected by a leading European
defense contractor for the development of a compact electronic warfare
platform.

The contractor will use Spectrum's flexComm SDR-3000 software
reconfigurable platform to provide advanced signal processing and
transceiver functions in its next generation mobile ultrawideband
jamming system. The system will incorporate Spectrum's SDR-3000 platform
in a compact, 2U configuration. The customer purchased two systems
valued at approximately $100,000 each for its development purposes and
expects to purchase an additional nine units for delivery in late 2005
or early 2006 for a lead end-customer deployment. The platform is
expected to be marketed internationally by the contractor as a catalogue
product to NATO-friendly customers.

"Electronic warfare applications have become an increasingly attractive
market opportunity for our software reconfigurable products, including
the SDR-3000," said Dan Simard, Managing Director of Spectrum's European
operations. "Much of our know-how in signals intelligence and military
communications is readily applicable to the electronic warfare market.
This expertise, combined with our ability to package the functionality
of our SDR-3000 into customized, deployment-scaled platforms, was the
key to our success in this design-in."

Spectrum's flexComm SDR-3000 is comprised of a heterogeneous processing
platform incorporating field programmable gate arrays from Xilinx® and
PowerPC® processors from Freescale™ and IBM. RapidIO™ provides a
high bandwidth interconnect fabric between the processors, as well as
the input/output functionality to the processors, to ensure efficient
use of the processing resources. Software development tools include
Spectrum's quicComm™ hardware abstraction layer to facilitate
algorithm partitioning and programming, and a real-time operating system.
