VoicePump, a DSP Group Company, Announces Easy-to-Use Starter Kit for Developing Voice over Broadband Applications

Company Exhibiting at Communications Design Conference Booth 324

SANTA CLARA, Calif., Oct. 2, 2001 — VoicePump, Inc., a wholly owned subsidiary of DSP Group (NASDAQ: DSPG), today announced the VP140 Starter Kit, a suite of development boards and digital signal processing (DSP) software that allows engineers designing voice-over-broadband (VoB) systems to evaluate the capabilities of the VP100 family.

The VoicePump VP140 -- the flagship product in VoicePump's VP100 DSP chip family -- is a mixed-signal device optimized for VoB customer premises equipment in offices, apartments and homes. With Broadband Loop Emulation Services and Internet Access Device functions already programmed on the chip, the VP140 is especially suitable for low-cost, four-port, Voice over Digital Subscriber Line (VoDSL) and VoIP applications.

"The VP140 Starter Kit's graphical user interface permits rapid analysis of the speech coding, echo cancellation and telephony signaling capabilities of the VP100 family, without the need to develop a custom prototype," said Cole Erskine, chief technical officer of VoicePump. "The kit will further shorten the development time normally associated with a DSP-based solution and reduce manufacturers' time-to-market."

The new Starter Kit, which sells for $1,100, includes the following hardware and software:

VP 140 evaluation board
FXO card
JTAG I/F card (JIC) with parallel-port cable
Power supply (for U.S.)
VP140 JIC PC software
VP140 DSP firmware demo
The shrink-wrapped kit is available now through VoicePump's distributors, worldwide representatives and the VoicePump web site.

About the VP100 Family

VoicePump's VP100 family devices integrate DSP Group's TeakLite® programmable DSP core with sigma-delta analog-to-digital and digital-to-analog converters -- thereby saving space in the design and lowering overall system cost. The VP100 family includes one-channel (VP110), two-channel (VP120) and four-channel (VP140) devices. A variety of speech coding and telephony applications are configurable on a per-channel basis via the VP100 family's flexible host-processor interface protocol. What's more, the chip's host port is compatible with all the popular packet-based host processors, including PowerPC, ARM, MIPS and others. VoicePump's corresponding source code and reference designs facilitate the ability of engineers to incorporate VP100 chips into their proprietary designs.
