TTPCom Delivering ARC-Based 2.75G Cellular Engine Designs To Silicon Designers Globally

ARC-Based™ CBEmacro Product Initial Result of Wide Ranging Agreement

SAN JOSE, Calif. and CAMBRIDGE, UK, November 29, 2004 – ARC International (LSE: ARK) and TTPCom (LSE: TTC), the world's leading independent supplier of digital wireless technology, today announced that the companies have partnered to deliver low-cost digital cellular engines to the burgeoning global handset market. Under the terms of a wide-ranging agreement, TTPCom has implemented ARC's configurable processor cores in the company's latest cellular baseband engine (CBEmacro) that is available to silicon designers globally. A demonstration of the ARC-Based™ CBEmacro product was given to customers and prospects at Japan's Embedded Technology show in Yokohama earlier this month. Other terms of the agreement include marketing and sales activities.

ARC's configurable processor technology proved to be a significant asset to TTPCom in the design of the CBEmacro product. ARC's unique CPU/DSP solution allowed TTPCom's designers to use a single architecture for TTPCom's dual core general purpose and DSP processing solution. TTPCom also obtained performance improvements in terms of memory usage, clock speed and power consumption using custom instructions created by the ARChitect™ processor configurator, a tool that allows engineers to quickly and easily customize an ARC core.

“The ARC-Based CBEmacro product represents a significant addition to our product line,” said Dr. Tony Milbourn, managing director of TTPCom. “Mobile handsets are increasingly differentiated by multimedia technologies and high-end application capabilities, rather than the underlying cellular engine. ARC's configurable processor technology enables us to easily provide the core cellular functionality, while ensuring that the design meets the critical cost parameters of cellular handset designers. ARC is strategic to our future product plans and we look forward to growing our relationship in the cellular marketplace.”

“Industry leaders are leveraging the benefits of ARC's configurable technology to create their next generation products without the bloat that is typical of other processor architectures,” said Carl Schlachte, president and CEO of ARC International. “TTPCom is a prime example of the increasing number of companies that are leveraging our technology to create cost-effective and innovative solutions to meet demanding market requirements. We are excited that TTPCom chose us for the EGPRS CBEmacro product and look forward to deepening the relationship as ARC extends its reach into the cellular arena.”
