SPECTRUM SIGNAL PROCESSING BRINGS PEAK PERFORMANCE TO DSP DESIGNERS WITH
ITS NEW MODULES

MDC40IL, MDC44T and MDC44S modules allow users to harness the power of
Texas Instruments' TIM-40 standard

Burnaby, B.C., Canada - March 30, 1995 - Spectrum Signal Processing Inc.
(NASDAQ NMS: SSPIF/TSE: SSY) announced two new products based on the Texas
Instruments (TIs) high-speed TMS320C44 DSP and a third that utilizes TI's
TMS320C40. These new modules will provide increased functionality with
Spectrum's wide range of TIM-40 modules.

The first two modules in the range are the MDC44T and MDC44S modules. Both
modules feature greatly increased memory capacity for applications
handling large volumes of high-speed data. The MDC44T combines two 50MHz
C44 processors with up to 8 MBytes of zero-wait-state SRAM - four times
greater memory capacity than previous-generation twin-processor TIM-40
modules. It has true Harvard architecture, allowing simultaneous data and
program fetches and maximizing the use of the C44's processing power.
Coupled with improved external access to the processor global memory bus,
this improvement dramatically increases flexibility for DSP designers.

The MDC44S has a single C44 processor on-board and up to 8 MBytes of SRAM -
over five times more memory capacity than Spectrum's MDC40S. In
applications such as graphics and imaging where large amounts of data need
to be processed rapidly, a large block of zero-wait-state memory is
essential.

The third module, the MDC40IL couples DSP technology with the
high-resolution and digitization rates of linescan cameras to open up new
applications such as web inspection in the steel industry. This module is
based on TI's TIM-40 modular hardware standard and can be included in
either PC or VME environments.

Spectrum's MDC40IL allows the user to acquire images from a variety of
linescan cameras, and in a variety of different formats, with line lengths
of up to 16,384 pixels. The MDC40IL will also accept simultaneous inputs
from up to four single-channel analog cameras, or a single TTL-level
digital camera. The 50 MHz C40 processor is backed up by 512 kBytes of
zero-wait-state SRAM and up to 16 MBytes of DRAM for program storage.

Volume availability in the second quarter of 1995 from Spectrum Signal
Processing.
