BSPs Offer Seamless SPOX Integration for Spectrum DSP Boards

FIRST BOARD SUPPORT PACKAGES, DEFINED BY SPECTRON MICROSYSTEMS SET FOR
LEADING BOARDS FROM SPECTRUM SIGNAL PROCESSING 

BURNABY, British Columbia, and Santa Barbara Calif., June 21, 1993--Two
leaders in advanced DSP-based technology today jointly announced the first
of a new set of software packages designed to speed and simplify
application development. 

Spectron Microsystems, Inc. and Spectrum Signal Processing introduced Board
Support Packages (BSPs) which customize the SPOX 2.0 real time kernel for
Spectrum's boards based on the TMS320C31 and TMS320C40 digital signal
processors. Designed and defined by Spectron, the Board Support Packages
work in conjunction with SPOX 2.0 to provide a turnkey environment for
application development using the Spectrum DSP boards. The BSPs deliver
device driver support for Spectrum's on-board peripherals and for popular
daughter modules. They also deliver DSP application-to-host
communications, stream and buffered I/O services for PC and VME hosts, and
C stdio extensions to the DSP compiler. 

The Board Support packages customize SPOX 2.0 for the C31 and C40 boards
and include the following features. 

* pre-configured SPOX installation utilities that support Spectrum board
configurations and enable users to build and run SPOX programs with no
additional system software development. 

* access to the full SPOX 2.0 feature set including multi-tasking interrupt
handling, memory management, real-time I/O and inter-processor
communications.

* multi-processing support including sophisticated intertask and
interprocessor communication services.

For the CV4 TMS320C40 6U VME Board (the TMS320C40 Multi-processor board),
the BSP will provide high performance single and multi-channel drivers for
communication between C40 processors and between C40 processors and
external devices.

The BSPs also support the following features of Spectrum's C31 and C40
boards:

* TMS320C40 TIM-40 modules, Link Interface Adapter, and dBeX/32 real-time
I/O peripherals on the CV4 VME Board.

* Analog Daughter Modules, Serial I/O, and dual-port SRAM PC interface on
the C31 Real-Time Applications Board.

"Spectron's BSPs provide all the hardware specific components necessary for
developers to get optimum application performance from the Spectrum DSP
boards," said Nancy Haydt, Spectron's Vice President of Marketing. "By
providing turnkey installation for SPOX 2.0, Spectron has made possible
for users of these Spectrum boards to cut in half the time it takes to
develop complex DSP applications."

Spectrum's TMS320C31 Real Time Board is the most cost-effective PC-based
DSP application development and is designed for high-volume OEM and
embedded system applications. Spectrum's TMS320C40 boards for the VME and
PC bus provide flexible scalable platforms for multi-processing
application development. With SPOX 2.0 and the Spectrum BSP, Spectrum C40
customers can develop multi-processing application initially with a single
processor and then rehost it - with no code modification--as more
processors are added to the board.

Pricing for the Spectrum BSPs begins at US $2,000. The C31 will be
available by the end of July, and the C40 BSP will be available by the end
of August 1993.
