Demonstrates Bluetooth Interoperability With Leading Silicon Platforms

LIVINGSTON, U.K.--(BUSINESS WIRE)--July 24, 2001--Tality Corporation, a subsidiary of Cadence Design Systems, Inc. (NYSE:CDN) -- today announced that it has established and verified stable interoperability between its Bluetooth Development System and products from Cambridge Silicon Radio, Ericsson, Philips Semiconductors and Texas Instruments -- leading providers of Bluetooth silicon platforms. The interoperability was demonstrated in an open forum -- the Bluetooth World Congress 2001.

``Establishing robust interoperability is a significant challenge in Bluetooth design. Our expertise in interoperability verification and debug is amply illustrated by this public demonstration,'' said Simon Jones, general manager of Tality's Bluetooth Business Group. ``The expertise, methodology and tools we employed in the demonstration are also the foundation of the open-access Bluetooth Interoperability Verification Facility Tality recently established.''

The products communicated on a piconet using Tality's development system -- which utilizes Tality's qualified baseband controller and protocol stack -- as the master. Three of the node links carried data, while the link to the Philips node carried both data and voice. The nodes were controlled via the standard host controller interface (HCI) by Tality's Bluetooth software development environment, Software Development Studio. It was also used to develop the demonstration, and to verify the interoperability of the systems.

Software Development Studio speeds the development of products that utilize Tality's upper protocol stack and any available extensions, such as application profiles. It verifies the interoperability of products that use Bluetooth baseband solutions conforming to the standard Bluetooth test control interfaces, HCI and L2CAP. Multiple external applications may simultaneously use Software Development Studio as a service provider, as illustrated by the demonstration. It is also used by Tality to verify interoperability at UnplugFests, and the proven test scripts may be purchased with the Studio.

Tality's Track Record in Developing Bluetooth Products

With 30 Bluetooth product and chip designs completed or in progress, Tality is a market leader in providing Bluetooth engineering services. Tality develops Bluetooth hardware and software intellectual property for use in its design services, and also licenses this IP to customers designing Bluetooth products themselves. Tality's product IP includes reference designs, an upper protocol stack, a full suite of application profiles, and their associated development tools.

Tality is one of only five adopter members invited by the promoters to join the Bluetooth SIG Radio Working Group, which is chartered with making significant enhancements to the Bluetooth 1.x specification.
