ARC's Patented Configurable CPU Helping Drive Fujitsu's Award Winning WiMAX SoC Solution.

ELSTREE, England -- With a 30 Percent Share of the Burgeoning WiFi Chipset Market, ARC's Architecture is Driving an Increasing Number of Mobile Wireless Products

ARC International (LSE:ARK), the world leader in configurable CPU/DSP processor cores and application subsystems, today announced that an ARC core plays a critical part in Fujitsu Microelectronics America's MB87M3400 WiMAX SoC. Fujitsu's WiMAX SoC has garnered worldwide renown as the leading broadband wireless processor in designing WiMAX-compliant base stations and subscriber stations. Early this month, the Fujitsu WiMAX SoC, which supports both licensed and unlicensed WiMAX bands between 2GHz to 11GHz, won "Product of the Year Award" from EDN China's Innovation Program.

About WiMAX

WiMAX is a rapidly emerging broadband wireless communications technology that promises to do for WiFi what the cell phone did for the cordless phone: provide high-speed wireless access over a much greater geographic area. And just as with the cell phone, WiMAX data communications can occur while traveling at highway speed. Furthermore, WiMAX connections are 20 or 30 times faster than a household broadband connection. In a Business Week Online article dated October 5th this year, Andrew Decker, chairman of the global telecom group at Bear Stearns Investment Banking, suggested WiMAX could become a disruptive technology in the next three to five years, thanks to the trend toward mass adoption of new technology in much less time.

About ARC's Patented Configurable SoC Technology

ARC's configurable technology enables SoC designers to create highly differentiated silicon that is optimized to the end application. ARC-Based(TM) SoCs have an optimal balance of speed, area and power, and generally are smaller, lower power and therefore less expensive than SoCs developed using fixed architecture CPUs.

Using ARC's configurable technology SoC designers can define custom extensions to accelerate critical code, resulting in greater application efficiency and a proprietary solution that is wholly owned by its inventor. ARC cores also offer powerful DSP instruction extensions through the ARC XY Advanced DSP subsystem, which can eliminate the need for external logic and DSP blocks on an SoC.
