Cypress Unveils Revolutionary West Bridge" Embedded Systems Architecture Enabling Rapid Data Transfer In A Variety Of Embedded Systems

New Family of Peripheral Controllers Provides a Bridge to Fast-Changing Interface Standards

SAN JOSE, Calif., November 27, 2006 - Cypress Semiconductor Corp. (NYSE: CY) today introduced a new architecture for dedicated peripheral controllers that serve as functional bridges to rapidly evolving interface standards and provide high-performance, optimized data paths for a wide range of embedded applications. Cypress also announced the first product based on this new architecture, a peripheral controller designed to optimize data throughput in multimedia handsets.  

Devices in the new West Bridge™ family of peripheral controllers function as a companion chip to an embedded central processing unit (CPU) to free it from data-intensive operations. In the same way the North Bridge and South Bridge were introduced in the PC architecture to enable the main CPU to evolve independently from quickly changing memory and peripheral interfaces, embedded systems are evolving towards a similar architecture, where a West Bridge device manages the interfaces and offloads from the main CPU specific peripheral-to-peripheral traffic. 

"West Bridge, the latest high-performance, programmable solution from Cypress, maximizes system performance and eases system design," said Dinesh Ramanathan, executive vice president of Cypress's Data Communications Division. "As a way to enable our customers to keep pace with changing interface standards, we plan to roll out a new version of these devices every nine months and a new generation of controllers every 18 months."

The West Bridge family is based on Cypress's Simultaneous Link to Independent Multimedia™ (SLIM™) architecture, which manages multiple, dedicated paths between peripherals, memory and the processor to allow maximum data throughput. In addition to providing a path to interfaces not supported by the main processor, the SLIM architecture allow direct and independent data transfer from one interface to another, offloading the main CPU, and freeing up its resources for higher system performance.

The first member of the family, the West Bridge Antioch™ controller, uses the SLIM architecture to provide a direct path in mobile handsets from High-Speed USB 2.0 to Mass Storage (NAND, SD, MMC, HDD) for rapid transfers of music files, photos and videos.
