DSP Group Announces New Release of C/C++ Software Development Tools for the Dual-MAC Teak DSP Core

Santa Clara, California, April 7, 2000 – DSP Group, Inc. (NASDAQ: DSPG), a leader in the development and licensing of high-performance, cost-effective digital signal processing cores, announced today the release of a new set of Software Development Tools for the TeakÒ DSP Core Digital Signal Processor. The highlights of the release include the powerful Teak DSP Core C/C++ Compiler, and the Modular Debugger and Simulator. The compiler is an enhancement of the OakDSPCoreÒ compiler that optimizes and maintains the efficient code generation and language extensions of the original OakDSPCore compiler, while adding support for the architectural enhancements of the Teak DSP Core.

The useful enhancements include 32-bit memory operations, improved hardware loops, and parallel instruction support. The Teak debugger and simulator enables convenient and flexible software debugging and testing. In addition, due to its modular design, it facilitates complete System-on-a-Chip simulation by supporting interface and interaction to other core debuggers and simulators.

Teak is the second member of the TeakDSPCoreÒ family. It is a Dual MAC 16-bit, fixed-point, licensable DSP with excellent code compactness. It is designed as a soft-core and targeted to low-power applications. Teak is aimed at higher performance-oriented applications such as cellular 3G, fast modems and VoIP Gateways.

"Software application migration from the OakDSPCore to the Teak DSP Core is an easy and fast process, with Teak's new tool set" stated Eyal Ben-Avraham, DSP Group's Director of SW Development Tools and Support. "For C/C++ code, the compiler takes advantage of the high-level language required by Teak's enhancements. In addition, C/C++ language extensions can be used to force an optimal code. Performance-critical areas that can benefit from the Teak enhanced architecture can be located using the Debugger's profiling capability, and implemented manually by assembly code" added Mr. Ben-Avraham.

The profiler tool, which is part of the Teak Debugger, can be used to gather statistics about the instructions used by the application, thus allowing the application developer to determine the critical kernels performance. Moreover, it allows the developer to determine architectural features used or those not used. The Teak Debugger is based on the modular Debugger architecture employed by DSP Group in its other cores. The Debugger architecture allows customization of its hardware interface to communicate with any kind of hardware emulation board. It allows easy synchronization with other debuggers in order to perform the multi-core debugging required for complex multi-core System-on-a-Chip designs.

The need for fast time-to-market and reduced development costs, along with the need for higher computing power, necessitates the reuse of application software, developed for previous generations of DSPs, in new powerful parallel architectures such as the Teak DSP Core.

The Teak DSP Core and its C/C++ set of tools answer these needs by supporting the wealth of existing OakDSPCore application code, while providing various code tuning and Teak adaptation capabilities. The new V8.1 SW development tools reflect DSP Group's ongoing commitment and dedication to continuing R&D and advancement in the DSP core product and technology lines, as well as maintaining its long-time reputation as a leading global provider of DSP core products and DSP core development technologies.
