ParthusCeva, Mentor Graphics and Accelerated Technology Announce Nucleus RTOS Support for Teak DSP Core

September 29, 2003

San Jose, Calif - September 29, 2003 - ParthusCeva, Inc.,
[(Nasdaq: PCVA); (LSE: PCV)], the industry's leading licensor of Digital
Signal Processor (DSP) cores and solutions, and Accelerated Technology®,
the Embedded Systems Division of Mentor Graphics Corporation (Nasdaq:
MENT), today announced a version of the Nucleus™ Real-Time Operating
System (RTOS) for embedded developers using ParthusCeva's Teak® DSP
processor. The combination of the Nucleus RTOS for the Teak DSP core
addresses the high-performance, high-volume needs of the multimedia and
cellular markets by providing developers with a scalable and robust
software solution on which to build embedded applications.

The announcement between ParthusCeva and Accelerated Technology
coincides with today's announcement of the release of a joint
specification by ARM and ParthusCeva for an architecture covering the
integration of ARM cores together with ParthusCeva DSP cores. This
specification defines a standard method for connecting DSPs with an ARM
core. The Nucleus RTOS supports both the ParthusCeva and ARM processor
cores.

With the rapid development of digital media-processing, developers
require a platform that can accommodate new technology yet maintain a
small memory footprint. Accelerated Technology's Nucleus RTOS, a leading
solution in the media-processing market, addresses these needs by allowing
multiple applications running at differing frame rates to co-exist on a
single DSP. By leveraging these benefits, Teak developers can quickly
build their multi-processing application, enabling rapid time-to-market
deployment.

"The availability of Nucleus software for ParthusCeva's DSP cores
greatly adds to our Media and Communications algorithm portfolio by
providing a robust multi-tasking RTOS platform on which ParthusCeva
licensees' can develop full application solutions supporting video, audio
and voice codecs (MPEG-4, H.263, AAC, MP3, WMA, FR, EFR, AMR) on a single
DSP," said Eyal Ben-Avraham, vice president of applications and support,
ParthusCeva, Inc.

"Nucleus software has been hugely successful in ARM-based devices like
mobile handsets in the wireless market. The integration of the Nucleus
RTOS with ParthusCeva's Teak DSP core enables us to provide the same RTOS
API on both the ARM and the DSP in the same design," said Robert Day,
director of marketing, Mentor Graphics Embedded Systems Division.

To address the needs of high-volume products, Accelerated Technology's
source-code, no-royalty business model will allow developers to save money
by not passing the costs of royalty fees on to their customers. A limited
version (LV) of the Nucleus PLUS kernel for Teak is available for download
from the Web site at http://www.acceleratedtechnology.com/.

Available now, licenses for the Nucleus RTOS start at U.S. $12,495. For

There are many hardware and software IP components integrated with Teak
and Nucleus software that are available to greatly simplify integration
effort of Teak licensees. Please contact ParthusCeva for more information

Teak is a 16-bit fixed-point general-purpose licensable DSP core. Teak
is a dual MAC architecture with parallelism capabilities. Designed as a
fully synthesizable soft core, it enables fast process and foundry
migration. The low power Teak DSP design as well as its high performance
makes it suitable to a wide variety of battery-powered portable
applications, including speech and audio processing, multimedia and
wireless communications (2/2.5 and 3G), high-speed modems, and various
embedded control applications.
