Transmeta Efficeon Defends Against Virus and Worm Attacks on Microsoft Windows XP

First Energy-Efficient Processor to Provide “No Execute” Support

May 17, 2004 -- Transmeta Corporation (NASDAQ: TMTA), the leader in efficient computing, today announced that its Efficeon microprocessor family will offer increased protection against many of the most common types of virus and worm attacks. This capability will be provided in conjunction with the Execution Protection feature shipping from Microsoft in the forthcoming Windows XP Service Pack 2 (SP2). New Efficeon processors scheduled to ship in mid-year 2004 and beyond will include “No Execute” (commonly known as “NX”) support as a standard feature.

In response to the growing threat of malicious virus and worm attacks on the Internet, Microsoft has announced plans for an upcoming release of Windows XP SP2, which will feature an integral virus protection feature known as Execution Protection, enabled only on systems with specific processor support. The Efficeon processor will provide this capability to protect against the execution of code from memory regions intended for data.

“Transmeta’s support for ‘No Execute’, working in conjunction with the safety features of Microsoft’s Windows XP SP2, will significantly reduce computer vulnerability to some of the most prevalent malicious code attacks,” said Matthew R. Perry, President and CEO of Transmeta Corporation. “Our release of cutting edge features aligned with Microsoft’s release of Windows XP SP2 yields a crucial solution for the future of computer security.”

Transmeta is providing advance versions of Efficeon-based systems with “No Execute” support to Microsoft this month for internal evaluation and use.

"Transmeta's unique software-based architecture can be rapidly extended to include new processor enhancements," Perry explained. "We were able to support Microsoft’s Execution Protection functionality without silicon changes, entirely within our Code Morphing Software -- the proprietary software that provides complete X86 functionality on our efficient VLIW processor hardware. Our architectural flexibility and the time-to-market benefits it enables are unique advantages that Transmeta provides, offering leading edge features to consumers and corporate customers more rapidly."
"Microsoft is always working to perfect our code, but with Windows XP SP2 we felt we needed a more holistic approach – one that involved hardware," said Jim Allchin, Group Vice President of Platforms at Microsoft Corporation. "By putting some of our best engineers together, Microsoft and companies like Transmeta have implemented Data Execution Protection. Customers using Transmeta’s new Efficeon processors will be much safer from attacks, since the processors and Windows XP SP2 will help prevent a whole class malicious code from running at all."
Some of the most devastating attacks, such as the recent Sasser worm and last year’s Blaster and Welchia worms, as well as many other malicious programs, attack computers by attempting to insert and execute code from data regions. The Execution Protection feature in Windows XP SP2 leverages the Efficeon processor’s “No Execute” support to stop this malicious code immediately if it attempts to execute. This combination of features will offer significant improvements against software worms and viruses, providing increased security for end users.

"’No Execute’ support guards against many of the most common and most devastating viruses and worms to date." said Rob Enderle, Principal Analyst for the Enderle Group. "These threats include the Blaster worm, which infected 1.4 million computers, racking up a cost of over $1 billion, and the Code Red which US Today estimated cost approximately $1.2 billion."

Transmeta’s Efficeon microprocessor will be the first energy-efficient processor to provide support for the “No Execute” capability, fully leveraging all virus and worm security improvements in Windows XP SP2.

About the Transmeta Efficeon Processor
The Transmeta Efficeon processor is designed to provide power efficiency, design flexibility, performance-on-demand and low cost to meet the need of the next generation of mobile, wireless, and embedded devices. It includes three new high performance bus interfaces: an on-chip HyperTransport™ bus interface for increased input/output efficiency, an on-chip Double Data Rate (DDR) SDRAM memory interface for increased throughput, and an on-chip AGP graphics interface for high performance graphics solutions. These new interfaces allow Efficeon to achieve more work per clock, which results in greater energy efficiency and longer battery life for mobile computer users. The Transmeta Efficeon processor's dynamic LongRun® power management features and integrated architecture are designed to give system designers and marketers a wide range of choices in creating products that deliver added value, functionality, security, comfort, reliability, and cost savings to end users.
