DSP Group and AXYS Design Boost Pre-Silicon Design and Verification with New TeakLite Model and Multicore Debugging Support

New Cycle-Accurate TeakLite® Model is Integrated into AXYS® Design's MaxSim™ Multicore Simulation Environment and the Mentor Graphics® Seamless® Co-Verification Tool

SANTA CLARA and PALO ALTO, California; August 8, 2002 - DSP Group, Inc. (NASDAQ: DSPG), the world leader in the development and licensing of Digital Signal Processor (DSP) cores and AXYS Design Automation, Inc. announced today the immediate availability of the fast cycle-accurate model for the popular TeakLite DSP core from DSP Group. The simulation model was developed using AXYS Design's MaxCoreâ tool and the processor description in C-based Language for Instruction Set Architectures (LISA). The MaxCore model delivers over one million cycles per second on a 1GHz Pentium host and supports scalable multicore simulation and debugging. DSP Group's thorough set of hardware test vectors has been applied to verify the functional match between the simulation model and its register transfer level (RTL) reference on a cycle by cycle basis.

Many electronic communication and consumer devices being created for the current market require Digital Signal Processing capabilities using limited power supplies and fast processing times to enable these devices to function efficiently. The TeakLite core is a 16-bit general-purpose DSP core targeted for applications requiring low power consumption, low bandwidth and high processing volume such as 2G and 2.5G wireless communication, as well as Internet audio formats, including MP3 and WMA, and Voice-over-IP phones. The new model of the TeakLite DSP core is part of the extensive MaxLibâ library of processor models for AXYS Design's MaxSimä Developer Suite. With MaxSim, users can create complete, application-specific platform models with multiple cores as virtual prototypes for early architecture exploration, pre-silicon embedded software development and multicore debugging. Early pre-silicon verification of hardware and software reduces the need for costly silicon re-spins and accelerates the product development cycle; thereby shortening the overall time-to-market. In addition to DSP Group's SmartCores™, the MaxLib library contains a rich set of models for other popular processor cores and System-on-a-Chip (SoC) components from ARM, MIPS and others.

"Our ongoing collaboration with AXYS Design in the system design methodology space is part of a strong commitment to our licensees, enabling them to achieve successful product releases of complex designs in the shortest possible timeframe." said Eyal Ben-Avraham, VP of Support and Applications at DSP Group's Ceva Licensing Division. "The newly-released high performance model is instrumental for efficient architectural trade-off analysis of multicore platforms, early development of embedded DSP software and simultaneous verification of hardware and software for designs incorporating our DSP core."

"The speed of the cycle-accurate and pipeline-accurate TeakLite simulation model, and the flexibility of our MaxSim multicore modeling solution, enable hardware-aware software development and trade-off analysis without compromising accuracy, at the earliest possible time," said Frank Schirrmeister, VP of Business Development, AXYS Design. "This level of accuracy is especially crucial for multi-core platform architectures incorporating the TeakLite DSP in which pipeline effects can significantly influence the performance of time-critical DSP applications."

AXYS Design also offers the cycle-accurate TeakLite model as part of the co-verification models available for the Mentor Graphics Seamless hardware/software co-verification environment. The new Seamless TeakLite Processor Support Package (PSP) will be available through the sales and marketing channels of Mentor Graphics.

At the ARM Partner Meeting, APM, (August 14-15, Cambridge, UK), AXYS Design and DSP Group will be demonstrating the dual-core MaxSim platform including DSP Group's TeakLite DSP processor and the ARM926EJ-S JAVA-enabled processor from ARM. Please visit AXYS Design at the APM (booth #112).
