Lockheed Martin Selects Spectrum flexComm SDR-3000
Platform for Advanced Communications System Development

COLUMBIA, MARYLAND--(CCNMatthews - June 1, 2004) - Spectrum 
Signal Processing Inc. (NASDAQ: SSPI / TSX: SSY), a leading 
provider of high performance solutions for wireless signal 
processing applications, today announced that its flexComm(TM) 
SDR-3000 software reconfigurable platform has been selected by 
Lockheed Martin Space Systems for the development of advanced 
communications systems. 

"We are pleased that Lockheed Martin Space Systems will be 
employing Spectrum's application specific platform offering," 
stated James Atkins, President of Spectrum Signal Processing 
(USA) Inc. "The SDR-3000 is the only high performance platform of 
its kind designed specifically for communications applications. 
Its capabilities are ideal for developing leading-edge systems 
for use in a variety of defense communications programs." 

The flexComm SDR-3000 configuration for Lockheed Martin combines 
high performance field programmable gate arrays from Xilinx(TM) 
and PowerPC(TM) processors from Motorola and IBM for signal 
processing. RapidIO(R) 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(TM) hardware abstraction layer to facilitate 
algorithm partitioning and programming, and a POSIX-compliant 
real-time operating system. 

"Spectrum's SDR-3000 platform combines integrated, high 
performance hardware with communications optimized software to 
enable the development of advanced signal processing systems," 
stated Chris Jelks, senior manager of strategic IR&D for Special 
Programs at Lockheed Martin Space Systems. "We will be using the 
SDR-3000 to develop foundational technology applicable to several 
communications-related programs."
