Parthus MobiStream GPRS Platform Receives Industry Accolades at 2001 3GSM World Congress for Solving Challenges of 2.5G Deployment

Dublin, Ireland and San Jose, California - February 26, 2001 -
Parthus Technologies (Nasdaq: PRTH; LSE: PRH), a leading developer of
semiconductor intellectual property for the mobile Internet market,
received widespread praise following the launch of MobiStream, one of the
industry's most advanced GPRS (General Packet Radio Service) platforms, at
the 2001 GSM World Congress in Cannes, France.

MobiStream combines the highest data rates and integrated multimedia in
one of the industry's lowest baseband power consuming solutions. Positive
reporting of the innovative Parthus solution have appeared in the some of
the leading business and technology news organizations, including AFX, CBS
Marketwatch, Dow Jones, EETimes, Electronics Times, Electronic News,
Financial Times and The Guardian to name a few. The research analyst
community was also quick to praise Parthus' innovative approach to solving
the challenges of 2.5G deployment.

"Without question, GPRS is a key milestone in the path to full
broadband mobile Internet connectivity," said Allen Nogee, senior analyst
at Cahners In-Stat. "The defining challenge for the wireless industry is
to deliver mobile devices at the cost and battery life consumers demand,
with a range of innovative data and multimedia applications. Parthus'
unique architecture and convergence strategy, as exemplified in the
MobiStream platform, is a major advance in solving these challenges."

Mobile operators worldwide are deploying GPRS to target the market for
mobile data services. With GPRS, connection is almost instant and users
can have 'always on' connectivity to the mobile Internet, enjoying
high-speed delivery of e-mails, Internet access and mobile multimedia
services. In Japan, always on connectivity through NTT DoCoMo's i-mode
service has been viewed as an inflection point for mass mobile Internet
adoption and usage. Cahners In-Stat forecasts that unit shipments of 2.5G
devices will top one billion units by 2004, while 2.5G semiconductor
revenue is predicted to grow to over $24 billion in the same timeframe.

"MobiStream is leading the industry in terms of the three critical
issues - power, price and performance - key to the success of 2.5G
roll-out," said Kevin Fielding, chief operating officer of Parthus. "We
are delighted by the industry's response to the launch of MobiStream which
clearly recognizes our commitment to converge complementary mobile
Internet technologies in a single chip solution."

MobiStream utilizes breakthrough dedicated silicon hardware
architecture to process and accelerate GPRS connectivity, while delivering
maximum GPRS data rates. MobiStream is architected to support multi-slot
Class 12 (maximum 4Rx, 1Tx), circa 56kbps with a simple software upgrade
to 8 slots/circa 115kbps as networks increase data capacity. In addition,
MobiStream leads the industry in terms of power consumption requirements,
with an estimated five-fold improvement over current generation GPRS
baseband solutions. The MobiStream baseband operates at 13MHz and
minimizes silicon area by requiring less than 100k gates and limited
RAM/ROM (7kbytes/3kbytes). The Parthus MobiStream platform is compatible
with Condat's GTI (Generic Target Interface) enabling the Condat G23
protocol stack family. Condat AG (NEUER MARKT: CDTG.DE), based in Berlin,
Germany, is a major supplier of G23 GPRS technology for 2.0G, 2.5G and
3.0G functionality.

As the MobiStream platform uses dedicated hardware for GPRS processes,
it off-loads the DSP for codec and mobile multimedia applications.
Multimedia capability is enabled by the Parthus MediaStream platform
allowing semiconductor companies and OEMs to deploy combined GPRS and
multimedia applications in a single chip. MediaStream will target a range
of audio applications (such as MP3 music download), Enhanced Messaging
Service standard (EMS is a planned upgrade of SMS) and ultimately the
Multimedia Messaging Service (MMS) 3G standard that allows a combination
of text, sounds, images and video to be streamed to any wireless device.

The MobiStream platform is designed to be deployed in a number of
configurations including data only (e.g., PDA, laptops, network cards);
data and voice (e.g., enhanced phones); and data, voice and multimedia
(e.g. Smartphones). As MobiStream is targeted at a range of standard CMOS
processes, it halves the cost of deployment compared with many
software-based GPRS solutions currently in the market. Cost savings are
particularly pronounced in data and multimedia deployments.


About MobiStream - The next generation in GPRS

Unique Architecture: MobiStream utilizes breakthrough dedicated
hardware silicon architectures for GPRS processing and interfaces to an
ARM 7-based (or comparable) microprocessor for software stacks. The
platform requires exceptionally low baseband size (<100k gates),
RAM/ROM (7kbytes/3kbytes) size.

Power Efficiency: Because MobiStream processes GPRS in dedicated
hardware running at only 13Mhz, the DSP is offloaded of these time
critical tasks and subsequently, power consumption is reduced.

Full Bandwidth GPRS: The platform is architected for 8 slots,
initially targeted at multi-slot Class 12 (maximum 4Rx, 1Tx), circa 56kbps
with a simple upgrade to 8 slots/circa 115kbps is possible as networks

Layer 2&3 Software Suites: Parthus is working with Condat to
integrate G23-GPRS into MobiStream. G23-GPRS is a fully portable protocol
stack for GSM/GPRS mobile terminals; a critical building block for all GSM
terminal manufacturers preparing for the next generation of packed data
mobile communications.

Low Cost Deployment: As MobiStream is targeted at a range of
standard CMOS processes, it halves the cost of deployment compared with
many software-based GPRS solutions currently in the market.

Flexible Deployment: MobiStream can be deployed in a number of

- data only - e.g., PDA, laptops, network cards
- data and voice
- e.g., enhanced phones
- data, voice and multimedia - e.g.,

Integrated Mobile Multimedia: MobiStream offloads the high-speed
processing tasks of multi-slot GPRS applications to dedicated hardware
freeing up the DSP primarily for multimedia applications. The MediaStream
24-bit DSP and accompanying library of software perhiperals enables the
multimedia feature.

RF Power Management: MobiStream also provides support for power
saving in the RF area by allowing the software to shut down various
portions of the radio and only bring them up just prior to their use.

Dynamic Loading: As the mobile device transitions through a wide
range of load conditions, from network acquisition to idle mode to
dedicated mode, dynamic loading varies the number of timeslots in use.

Foundation for EDGE: The Parthus baseband architecture has been
developed with EDGE in mind. The overall architecture remains very
similar, supporting GSM, GPRS and EDGE functionality in a single core.

Convergence Roadmap: Parthus offers an unrivalled portfolio of
platforms powering the computing, communications and content requirements
of next generation mobile Internet. By converging Parthus' 2.5G,
Bluetooth, GPS, mobile computing and multimedia platforms onto a single
digital chip, companies can overcome the cost, power and form factor
challenges of next generation mobile devices.
