ARC International Receives Second Full-Speed OTG Certification from the USB-IF

SAN JOSE, Calif., November 24, 2003 – ARC International (LSE: ARK), a world leader in user-customizable processors, silicon peripheral IP, real-time operating system and development tools for embedded system design, announced today the Company's USB-HS OTG product has received its second Full-Speed On-the-Go USB-IF Certification.

“This is the second product for which ARC has attained the coveted On-The-Go logo,” said Bernard Glasauer, Sr. Vice President of Peripheral IP at ARC International. “The addition of the ARC USB HS-OTG controller core to the USB-IF's integrators list offers our customers additional choice and flexibility when implementing USB On-The-Go functionality. It is one more example of how ARC provides the widest and deepest set of USB IP solutions to the market.”

• ARC's USB-HS OTG is the industry's leading solution for High Speed and Full Speed OTG applications. It incorporates an innovative architecture, including a protocol-aware DMA controller. Benefits include: Reduced total die area (inclusive of endpoint buffers) in real-world, full system implementations
• Reduced system processor and system bus loading
• Most mature product available today: ARC has been shipping the USB High Speed OTG product since September of 2002, and leads the industry in both design-ins and silicon implementations
• Full suite of verification tools
• Most mature OTG software stack. The ARC stack can use Task, Event, Message Passing, Interrupt or Semaphore based OS structures, and offers a thin hardware adaptation layer for ease of porting. The stack can work standalone in those systems that do not use an operating system.

ARC's USB HS OTG product is delivered as fully synthesizable RTL code, available as VHDL or Verilog, and is available with BVCI or AHB interfaces. Delivery also includes driver source code, full verification suite and extensive documentation.

Earlier this year, the company introduced the ARC CertiPHY program whereby the industry's leading PHY manufacturers work with ARC to verify that their PHY's work with ARC's USB technology. This innovative program was introduced as ARC's solution to an industry-wide problem, and aids SoC developers with interoperability testing which, in turn, eases USB-IF certification.
