Dublin, Ireland - September 4, 2001 - Parthus Technologies plc
(Nasdaq: PRTH, LSE: PRH), a leading provider of platform level
intellectual property (IP), today announced a licensing agreement with Sun
Microsystems for the joint development and deployment of Java™
technologies targeting wireless devices based on the Parthus MachStream
platform. This initiative will allow major electronics developers and
manufacturers to deliver Java technology-based multimedia wireless devices
with "PC-like" levels of performance and extended battery life.

Under the terms of the agreement:
Sun
Microsystems has certified the Parthus MachStream acceleration technology
for use in Java technology-based platforms by wireless device developers
and manufacturers.

Provision is made for early access by wireless device developers to Sun
technology for development of upgrades to MachStream.

Licensing of Sun's reference implementation and alignment with Sun's
roadmap for security encryption (SSL, HTTPS) under the J2ME-MIDP
specification.

Java technology, with its 'write once, run anywhere' capability is
recognized as a core technology for next generation mobile Internet. Java
technology-based phones are already available in Japan and Nokia recently
forecast that they will ship over 100 million Java technology-enabled
phones by 2003 resulting in a common software standard for a myriad of
wireless applications.

Java technology provides the benefit of being hardware/processor
agnostic.Combining Java technology with MachStream for mobile devices
moves processor intensive software tasks into a high performance low power
silicon accelerator targeted at any type of RISC or DSP processor,)
resulting in dramatic performance and power efficiency improvements. A
recent benchmark study by the Microprocessor Report noted that the Parthus
MachStream Platform delivers superior processing and power performance
over principal competing approaches.

"Parthus Technologies is approaching applications acceleration with a
comprehensive platform for OEM and device manufacturers. Parthus' unique
approach delivers some of the best Java technology performance for
wireless devices and exemplifies the 'write once, run anywhere' Java
vision," said Rich Green, vice president and general manager, Java and XML
Software for Sun Microsystems, Inc. "With proven J2ME technology, Parthus
can deliver targeted solutions to enrich the user experience."

MachStream is unique technology as it accelerates the entire suite of
wireless applications including Java technology, wireless media processing
and emerging applications based on the Java 2 Platform, Micro Edition™
(J2ME™)-MIDP platform such as multimedia, security encryption, web
browsing (XML, XHTML) and interactive games. In relation to gaming alone,
Strategy Analytics Report (April 2001) there will be 100 million mobile
game users worldwide by 2006 and that the gaming market alone will be
worth $5B per year.

"We see Java as a fundamental technology for the next generation mobile
Internet economy and we are delighted to be collaborating with Sun to
deliver the industry's best Java platform to deliver on this promise,"
said Brian Long, chief executive officer of Parthus. "Our customers and
partners are hugely excited by the prospect of accelerating Java
technology, multimedia, security, gaming and web browsing through one
common power efficient platform and thereby opening the capability for a
wide array of new wireless delivered applications."

Parthus Technologies, a leader in IP platforms for GPS (Global
Positioning Systems), Bluetooth, MPEG IP and 2.5 and 3G technologies,
delivers complete IP solutions to several of the world's largest
semiconductor and device manufacturers. Parthus launched the MachStream
Acceleration Platform in May of 2001 focused on accelerating multiple
aspects of applications on mobile devices including Java technology-based
applications that require the use of a Java virtual machine and
compression of application and data files (JAR, PNG). End of press

About MachStream

The MachStream platform is a modular, silicon-based intellectual
property engine that substantially boosts the performance and
significantly decreases the battery power requirements for multiple
aspects of the wireless applications environment. MachStream moves
computationally-intensive portions of the mobile Internet applications
infrastructure into high performance, low-power silicon. Unique Features
of MachStream include:

Multi-application acceleration - By utilizing advanced JIT
(just-in-time) technology the MachStream engine contains multiple silicon
accelerators, each aimed at speeding and saving battery power for a wide
range of wireless applications, including:

Complex open software applications (Java
technology)
Mobile
multimedia (various media applications)

Streaming media (streaming video)

Security Encryption (SSL, HTTPS)

Wireless browsers/scripting languages (cHTML, XHTML, XML or WML-based)

Single-chip capabilities - The MachStream engine can be easily
integrated into a system by attaching it to a standardized hardware
interface. The engine is designed to be implemented along with the main
processor as a single-chip solution, but can also be implemented as a
second chip or even integrated within a memory controller or other
device

Power consumption and performance - MachStream's advanced JIT
technology takes long streams of Java byte codes and compiles them in real
time into highly optimized streams of native instructions. Recent
benchmarks using CaffineMarks have shown that Java technology performance
is boosted on average 10-15X with peak performance up to 35x. This unique
low power implementation consumes less than 0.1Mw/ MHz at 1.5 volts - only
when actively translating and optimizing Java byte code streams. Studies
show that battery power used for running Java technology-based
applications is improved by almost ten-fold in a Smartphone systems
deployment. In addition, no operating system or application modifications
are required to take advantage of the platform's acceleration
capabilities

Hardware and software - MachStream is available as a synthesizable
RTLcore in VHDL or Verilog formats. Customer-specified formats will be
provided as required. A reference implementation and accelerated demo
applications are available for evaluation

Cost and time-to-market - MachStream delivers minimal incremental cost
increases by combining ultra small silicon size with the integration of
the IP into the system SoC. This approach allows developers to take full
advantage of shared resources through a single architectural platform

Mach I & II acceleration - Code translation and data and media
pre-processing - The MachStream platform uniquely combines code
translation and optimization, and data/media pre-processing to attack
power consumption and processing speed from two angles.

Mach I - Code stream translation and optimization of
applications written in open standards and processed and stored in
hardware: e.g. Java technology accelerator

Mach II - Media/data pre-processing of
application-specific file types: e.g. PNG, JAR and ZIP
