Parthus launches InfoStream, the Industry's Most Advanced Mobile Internet-on-a-chip Platform for Next Generation SmartPhone Devices

San Jose, California/Dublin, Ireland - October 18, 2000 -
Parthus Technologies PLC (Nasdaq: PRTH, LSE: PRH), the leading developer
of platform level intellectual property for the Mobile-Internet market,
today announced the launch of InfoStream, the world's most advanced
Mobile-Internet computing platform on a single chip.

Co-developed with Psion PLC (LSE: PON.L), InfoStream is designed to be
the silicon platform for next generation wireless Internet devices,
including 3G Smartphones, Communicators, PDAs, automotive, Internet
appliances and wireless portable tablets. InfoStream leads the industry in
processing power, power consumption requirements and levels of on-chip
integration. The technology enables device manufacturers to drastically
reduce time to market for next generation wireless Information

The launch of InfoStream coincides with the announcement today that
Psion has signed a licensing and royalty agreement with Parthus to power
its next generation PDAs and for Motorola's next generation Smartphones.

"With the growth of mobile data services expected to skyrocket within
the next few years, the Parthus InfoStream platform, co-developed with
Psion, is well positioned to be a major market player in the next
generation of Internet enabled mobile devices," said Allen Nogee, senior
analyst at Cahners In-Stat Group.

The InfoStream platform is powered by Symbian and the ARM, and is
designed to take mobile computing to the next level by combining the rich
features of the PC with Internet access and mobile phone capabilities,
commonly know as Smartphones. The market for such devices is predicted to
explode in the next three years.Cahners In-Stat Group forecasts that the
number of mobile data/Internet subscribers will exceed 740 million by
2004. These devices allow users to surf an 'always on' web, read emails or
instant messages, store PIM data (e.g., address books), synch with their
PC and even word process (InfoStream can accommodate keyboard or phone pad

While InfoStream has been designed to power Symbian, the platform also
supports a range of other operating systems, including Pocket-PC, Palm and
Linux. InfoStream's modular architecture is optimized for key technologies
such as GPRS broadband wireless communications, Bluetooth™ for
wireless local area networking and GPS for location based services. These
are all core technologies within the portfolio of Parthus intellectual
property for the Mobile-Internet.

"Tomorrow's handheld devices will combine a rich array of features and
functions, and we believe Psion is uniquely positioned in the world of
mobile computing to play a leadership role in this market," said David
Levin, CEO of Psion. "By developing the InfoStream platform in partnership
with Parthus we are able to deliver the most advanced mobile computing
technology available in the market today. Not only will this platform
power next generation Psion Mobile-Internet devices, but also a range of
Motorola Smartphones."

"The launch of InfoStream silicon platform provides key advantages for
manufacturers of Smartphones and Communicators," said Colly Myers, CEO of
Symbian. "Optimised for Symbian's software platform, InfoStream provides
key performance and memory management capabilities, offers flexible
configurations, and combined with the ARM 9 core provides a solution
enabling rapid time to market for wireless Information devices."

"We are entering the era of mobile, connected computing and
communication," said Brian Long, chief executive officer of Parthus. "By
delivering the Mobile-Internet on a chip, InfoStream helps bring us closer
to the true pervasiveness of next generation Smartphones that will harness
the power of the Internet, the PC and the mobile phone through one
handheld device. With our partnership with Psion, Symbian and ARM, Parthus
is perfectly poised to deliver on that promise."

Unique Features of InfoStream Include:

Combining Processing Performance With Low Power:

InfoStream combines unparalleled processing power with extremely low
power consumption, both critical design criteria for next generation
data-centric handheld devices. The ARM 920T powered platform delivers
200MHz at 2.5V or 150MHz at 1.8V. Extensive power management features such
as clock gating techniques deliver ultra low power consumption.

Flexibility In Operating System:

While InfoStream is optimized for Symbian, the OS of choice for next
generation Smartphones, the platform can equally run Microsoft Pocket PC,
Linux and Palm OS. Symbian delivers superior performance and graphics and
is fully optimized for GPRS and Bluetooth. It also delivers the
richest array of applications to be found on the handheld platform,
including PIM applications, such as contacts database, agenda, world
clocks; Communications, such as email, short messaging etc; Office, such
as word processing, spreadsheets etc; Games; and Data Sync with PCs and
other devices.

Modular Architecture for Rapid and Flexible Deployment

In the rapidly changing Mobile-Internet market, swift upgrades and
feature additions are critical to maintaining competitive advantage.
InfoStream exploits a modular architecture enabling system OEMs to rapidly
add customized features and upgrades (with over 60k available pins). Due
to the soft IP configuration of the technology, InfoStream allows
semiconductor and wireless/handheld OEMs to target a vast array of devices
and environments, such as Smartphones, PDAs, 3G Mobile-Internet devices,
telematics or wireless tablets (such as courier tablets) for logistic
