New Development Board for TI "Wireless" DSP

Sunnyvale, CA (May 13, 1996)-- DSP Research announces the release of the
TIGER 542/PC, a new DSP development system based on the new generation of
digital signal processors from Texas Instruments. The PC/AT board targets
DSP software and system developers using the TI TMS320C54x DSP. 

The TMS320C54x DSP: A New Generation of DSPs 

The TMS320C54x family maximizes performance while reducing power
consumption and system cost for high-volume, wireless communications
applications such as digital cellular telephony, pagers, personal digital
assistants (PDAs), and wireless modems. 

The 'C54x family features a Viterbi accelerator for reducing Viterbi
"butterfly update" and three power-down modes for extended battery life in
mobile applications. The 'C542 incorporates two serial ports (one
buffered, one TDM), an 8-bit host port interface, 10k words on-chip RAM
and 2k words on-chip ROM. Although the 'C54x DSPs are optimized for
wireless communications terminals, they are also suitable for all
telecommunications applications. 

TIGER 542/PC: Rich in Features 

Each TIGER 542/PC comes with up to 256 Mbytes of zero wait state static RAM
on board. Input and output features include two channels of 16 bit, 50 kHz
CD quality analog I/O, with standard stereo mini phone jacks for
microphone and line level input, and line output. 

For fax and modem applications, the TIGER 542/PC has a built-in standard
RJ-11 telephone interface, FCC part 68 approved. The on-board RS-232 UART
can be used to configure the board to emulate a standard modem or fax
machine. 

The TIGER 542/PC supports several host communications options. A 16-bit
register interface allows for transfers between the host and the 'C542. In
addition, interrupts between the host and DSP are supported. For direct
host access of the 'C542, the Host Port Interface of the 'C542 can be
mapped to the ISA bus. The TIGER 542/PC can also be configured for
stand-alone operation. In this mode, the on-board EPROM and RS-232 UART
can be used for downloading programs and controlling the board from a
standard PC. 

The TIGER 542/PC development tools include Texas Instruments Optimizing C
Compiler with Assembler, Linker and Loader, and the DB5xx C Source Level
debugger in both DOS and MS-Windows versions. 

For rapid software development, the TIGER 542/PC comes with the TIGER
QuickSTART Operating Environment. The QuickSTART software provides the DSP
programmer with a complete software development environment, including
device drivers, DSP memory allocation, buffer handling, and standard I/O
to the host computer (including graphics and file I/O). 

Pricing for the TIGER 542/PC board starts at $1695 USD. Software
development packages including a board start at $3295 USD. For more

DSP Research has been an important presence in the Digital Signal
Processing field since 1989. The company offers a full line of development
systems and emulators for TMS320C3x, TMS320C4x, TMS320C5x, and now
TMS320C54x processors.
