Tower Semiconductor Licenses DSP Group's Teak DSP Core for Fab 2
MIGDAL HA'EMEK, Israel and SANTA CLARA, Calif., Jan 2, 2002 /PRNewswire via COMTEX/ --

To Be Used in Cellular Communication, Multimedia, Digital Cameras And Speech/Audio Applications

Tower Semiconductor Ltd. (Nasdaq: TSEM; TASE: TOWER), a leading Semiconductor specialized foundry in Israel, and DSP Group, Inc. (Nasdaq: DSPG) the leader in the development and licensing of high-performance, low-power, digital-signal-processor (DSP) cores, today announced that Tower Semiconductor has licensed DSP Group's Teak(R) DSP Core.

"This agreement significantly expands our Semiconductor Intellectual Property (SIP) offering in Fab 2. Customers for our state-of-the-art 0.18 micron Industry Standard process technology will be provided with a fully ported, silicon validated Teak core," said Mr. Ishai Nachumovsky, Tower's Senior Director of Foundry Technologies. "The agreement will play a major role in enhancing Tower's LSI offerings in applications where high-performance signal processing is required, and provide Tower's customers with a competitive edge, shorter design cycle, and easy integration of a leading DSP core into their Systems-on-a-Chip (SoC) designs," he added.

"We are very pleased with Tower's choice to offer our technology to its customers for their designs and consider it a vote of confidence for our advanced DSP technology," said Mr. Issachar Ohana, VP Sales of DSP Group's Technology Licensing Division. "We believe that the unique combination of high performance, low-power dual-MAC architecture with Tower's high-end process will offer great benefits to the two companies' customers," he added.

Teak DSP Core, SmartCores(TM) family fourth generation core, is a high-performance, 16-bit fixed-point DSP core using a Dual-MAC (multiply-accumulate) architecture that enables a peak performance of 420 MIPS. Teak has a parallel instruction capability and performs high-speed interrupts and fast context switching. It also includes an extended program addressing space and parallel instructions that accelerate the performance of various DSP algorithms. Teak is known for its code compactness, and has excellent program memory utilization that reduces the die cost. Teak also has special proprietary mechanisms designed to reduce power consumption and other micro-architecture modifications. Teak was designed for use in DSP-based ASICs, is fully code-compatible with DSP Group's OakDSPCore(R) and TeakLite(R) and offers a natural migration path for designs made using previous generation cores, but which require a higher level of performance.

This core complements Tower's portfolio of building blocks for implementation of high-end processing, imaging, storage and multimedia applications: embedded flash and EPROM blocks, embedded CMOS Image Sensors, Mixed Signal capabilities, a variety of compiled ROM and SRAM options and comprehensive standard cell and I/O libraries.
