Prairiecomm Licenses Dsp Group's High-Performance Digital Signal Processing Core Technology

DSP Group's TeakLite® Technology Provides PrairieComm with a Platform for Next-Generation UMTS Baseband Processors

ROLLING MEADOWS, Ill. and SANTA CLARA, Calif.—October 2, 2001—PrairieComm, Inc., a leading provider of chipsets for wireless handsets from the world's leading consumer electronics manufacturers, and DSP Group Inc., (NASDAQ: DSPG), the leader in the development and licensing of high-performance, cost-effective digital signal processing (DSP) cores, today announced they have entered into a strategic DSP technology licensing agreement. Under the terms of the agreement, PrairieComm has licensed DSP Group's TeakLite technology as a platform for developing its next-generation solutions for wireless communications.

The licensing of TeakLite technology augments PrairieComm's extensive portfolio of wireless solutions, which includes chipsets, embedded software and licensed intellectual property for CDMA, TDMA, GSM and 3G UMTS.

"DSP Group's TeakLite technology gives PrairieComm a solid foundation for building the highly integrated chipsets for today's and tomorrow's 3G baseband architecture," said Ed Roney, PrairieComm's Vice President of Products and Systems. "The power efficiency and performance of TeakLite technology will significantly enhance our product designs for third-generation wireless chipsets."

The PrairieComm PCI5110, an advanced multi-mode integrated baseband processor that supports the UMTS standard for 3G cellular communications, uses TeakLite technology. Incorporating both WCDMA and GSM technologies, the PrairieComm PCI5110 also enables GPRS for high-bandwidth mobile communications. PrairieComm is currently providing samples of this chip to its customers.

"As the newest member of DSP Group's SmartCores™ adopters, PrairieComm will apply our enabling technology to a new generation of baseband solutions which are optimized for high-performance UMTS products," said Bat-Sheva Ovadia, DSP Group's Vice President of Marketing and Business Development. "Since our broad, licensable DSP core product line is compatible with PrairieComm's advanced low- power 2G/ 2.5G/3G offerings, PrairieComm will be able to use our cores together with its engineering talent, systems knowledge, and understanding of the market to make groundbreaking contributions to the drive to bring UMTS products to market."

TeakLite, the third generation of the SmartCores family, is a 16-bit fixed-point, general-purpose DSP core designed for low power, low voltage and high-speed digital processing applications. The core is designed as an ideal solution for speech and audio processing, wireless communication (GSM, CDMA, TDMA, EDGE, GPRS, 3G, etc.), modems, advanced telecommunication systems, disk-drive controllers and embedded control applications. Because the TeakLite DSP core is binary code compatible with the DSP Group's OakDSPCore®, it effectively eliminates the need to recompile or rewrite existing software modules during migration to the TeakDSPCore® family. The fully synthesizable, process-independent TeakLite is easily portable to any Application Specific Integrated Circuits (ASIC) library. The core can be used as an engine for DSP-based-ASICs, and is available as a DSP core in a standard-cell library applicable for custom chip design. As a result, the design of the core provides several levels of modularity in RAM, ROM and I/O, which allows efficient DSP-based ASIC development. Further, the core is designed in a single-edge clocking system, which allows the use of full or partial scan testing methodologies. The core also supports emulation, debugging and testing via JTAG.
