USB-IF Certifies Full-Speed OTG From ARC International

SAN JOSE, CA, September 4, 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 Full-Speed On-the-Go products had received USB-IF Certification.

“This is the first time the USB Implementers Forum has offered USB Compliance Testing for full-speed OTG,” said Andy Haines, senior vice president marketing at ARC International. “It is our goal to submit all our USB technology for Compliance Testing at the earliest opportunity, so our customers can be confident products will work as specified without them having to spend additional design cycles on their implementation.” ARC’s USB FS OTG product features the following benefits:

• Lowest gate count (inclusive of endpoint buffers) in real-world, full system implementations
• Includes DMA
  
• Most mature product available today: ARC has been shipping Host/Device product since 1998, OTG product since 2000, and leads in OTG implementations in silicon.
  
• 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 FS 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 works with ARC’s USB technology. This program was introduced to aid SoC developers with interoperability testing which, in turn, eases USB-IF certification.
