San Jose, Calif./Dublin, Ireland - August 30, 2000 - Parthus
Technologies plc (Nasdaq: PRTH, LSE: PRH), a leading developer of
semiconductor intellectual property (IP) for the Mobile-Internet market,
today announced the launch of NavStream™, a GPS (Global Positioning
System) platform that delivers unrivalled positioning accuracy across a
range of Mobile-Internet devices including mobile phones and
automobiles.GPS is a cornerstone technology for the next generation
Mobile-Internet market, offering core benefits to operators and end users.
NavStream is capable of delivering location accuracy of less than five
meters in under ten seconds anywhere in the world.

The launch of NavStream coincides with the announcement today that ARM
(LSE: ARM); (Nasdaq: ARMHY), the industry's leading provider of 16/32-bit
embedded RISC microprocessor solutions, will incorporate NavStream into
its core technology offerings. In addition, ARM will sub-license the
NavStream platform to its global network of customers and partners
ARM.

GPS (Global Positioning System) processes information from 24
satellites orbiting 11,000 miles above the earth to determine the
latitude, longitude and altitude of a user's GPS-enabled mobile phone or
car. Unlike Network Centric approaches to location, GPS delivers superior
accuracy, speed in location fix, and works in any environment - urban,
remote and globally - for today's roaming consumer.

For example, if a user's car breaks down on a busy freeway, emergency
services can determine whether the car is located on the right or left
side of the road. Equally, parents can keep track of their children's
exact location by embedding GPS technology into a watch or other device,
giving them peace of mind.

NavStream™ complies with the recent US Federal Communications
Commission (FCC) mandate that requires all cellular carriers in the US to
be able to locate cellular callers instantly to emergency 911 services by
October 1, 2001.

GPS also offers many commercial opportunities to wireless operators
through 'location-based m-Commerce'. It is envisaged that m-Commerce
services will be driven by localized service and product offerings. GPS
technology allows mobile operators to offer users many services, including
real-time driving directions, traffic information and personalized
concierge services, such as nearby restaurants, stores, ATMs, and places
of interest. As GPS becomes ubiquitous in cars and mobile phones, the
technology can be used to pay for road tolls, parking fees and securing
valuable items.

"GPS is a cornerstone technology of next generation Mobile-Internet and
our goal is to make NavStream™ the dominant GPS standard for the
Mobile-Internet industry," said Kevin Fielding, Chief Operating Officer,
Parthus Technologies. "The NavStream™ Platform leads the industry in the
four critical areas for implementing GPS in mobile phones - low cost, low
power consumption, pinpoint accuracy and noise immunity. The successful
launch of the NavStream™ platform is a powerful endorsement of the success
of our acquisition and integration of the GPS division of Symmetricom."

About NavStream™

NavStream is a complete GPS based Platform encompassing Radio, Baseband
and Software stacks targeted at mobile phone and automotive markets.
NavStream is deployable either in a single chip, GPS radio with GPS
baseband integrated into host processor, or uniquely in a 'zero chip'
configuration which encompasses a multi-mode GPS / Bluetooth™ radio and integrated
baseband.

The NavStream™ Platform encompasses:

SiGe RF: Delivers very high sensitivity enabling GPS
reception in challenging environments such as in buildings, urban canyons
and deep foliage. A key feature is the ability to reject out of band
interfering signals - a key issue in cellphone integration.

0.18CMOS GPS/Bluetooth Multi-Mode RF: This highly
integrated radio delivers lowest cost for implementing GPS in wireless
handsets. When combined with the integrated GPS Baseband, this 'zero chip'
deployment delivers, at under $4, the lowest cost in the industry to
deploying GPS in handsets. The radio is highly configurable and can
operate in either GPS or Bluetooth only mode or combined
GPS/Bluetooth mode. Availability in Q3 2001.

NavStream Baseband: Targeted at the ARM 7 processor (and
fully AMBA compliant), the NavStream Baseband uniquely enables the vendor
to select the number of GPS complex correlators for the device. Extending
GPS correlators greatly speeds time to first fix of location.

NavStream Protocol Stacks: An extensive suite of software
stacks of tracking, navigation and accuracy. The Platform will also
include a GPS DSP that further accelerates time to first fix, particularly
in challenging environments such as inside buildings. A range of software
enables the Platform to be targeted at wireless handsets, automobiles,
timing, avionics markets. All software stacks are modular in architecture
minimizing required RAM for embedded environments (<180kBytes).

NavStream™ delivers unrivalled location accuracy (locates users to
under five meters) to any device, be that a mobile phone, PDA (Personal
Digital Assistant) or GPS enabled vehicle. NavStream™ is architected to be
air interference independent and operates inside houses, moving vehicles,
under heavy foliage and in dense city locations across the globe.
Established and proprietary hardware and software techniques maximize
sensitivity (-176dbwW), eliminate frequency jamming and minimize power
consumption.

NavStream™ Market Drivers - Users

Meanwhile, NavStream™ delivers a host of advantages to users. These
include:

Unrivalled accuracy - While most networked-based location
technologies can locate the user to within a range of 100 meters,
NavStream™ utilizes a GPS (network independent) approach to locate the
user to within 5 meters

Speed - Unlike many GPS technologies, NavStream™ can
pinpoint the location of an individual in a matter of seconds

Privacy - Because NavStream does not depend on networks to
determine a location, users can choose to keep their location private from
third parties

Security - The technology incorporated into NavStream™
ensures that users can signal their location quickly and accurately

GPS Everywhere - Being an ultra high sensitive GPS Platform,
NavStream™ can work practically in any environment: cities, inside
buildings, urban canyons, deep foliage, remote rural environments.
Moreover, GPS operates globally unlike national proprietary standards.
