Ottawa, Ontario, Canada Following its introduction in February of the industry's first serial RapidIO switch, the Tsi568A, Tundra Semiconductor Corp. has added to its product portfolio another device that is cheaper and smaller but delivers the same performance to build high-performance communications systems.
The Tsi564A serial RapidIO switch measures 21-mm x 21-mm compared with Tsi568A's package size of 27-mm x 27-mm package. It offers low-power multiple port widths and speed configurations, and supports 40-Gbits/s aggregate bandwidth.
Based on the Serial RapidIO Specification, the Tsi564A incorporates SerDes functionality, error recovery, priority-based fabric routing, high payload efficiency, and table-based fabric packet routing. In addition, the Tsi564A supports RapidFabric extensions, including data streaming packet switching for encapsulation.
RapidIO technology is a packet-switched, interconnect and fabric technology that is addressing the embedded industry's need for increased bandwidth and faster bus speeds. It is designed to enhance performance of communications processors, host processors, and networking digital signal processors, and allows chip-to-chip and board-to-board communications at performance levels scaling to 10 Gbits/s and beyond.
The Tsi564A goes beyond standard specification requirements to solve system level issues with low power consumption, and hot swappable I/Os. The extensive buffering and traffic management architecture is specifically designed for line rate termination and the prevention of head-of-line blocking.

"By introducing a lower cost, smaller footprint switch backed by our industry leading support tools, we are demonstrating our continued commitment to enabling our customers' success in advanced system interconnect," said Rick O'Connor, chief technology officer and vice president of product management at Tundra. "Tundra continues to develop system interconnect products that build on our innovative switch fabric technology, providing increased performance and configurability not feasible with proprietary bus-based architectures."
PCI Express (PCIe), the next-generation serial bus-interconnect standard, is challenging widespread adoption of RapidIO. PCIe is the dominant bus standard in computing applications, while RapidIO is designed for the networking, storage and communications systems. However, as microprocessor clock speeds continue to increase, RapidIO proponents say bus architectures cannot meet system bandwidth requirements.
In addition to Tundra, Texas Instruments is supporting RapidIO and recently introduced the TMS320C6455, the first DSP developed using serial RapidIO technology.

According to Paul Mesibov, director of engineering at Pentek Inc., a manufacturer of advanced analog and digital I/O products, the Tsi564A serial RapidIO switch "provides the performance required by increasing I/O bandwidth found on next-generation processors. The Tsi564A switch and TI's C6455 DSP with integrated serial RapidIO provide a range of solutions that optimize performance, power efficiency, and the flexibility required for our next-generation platforms."
The Tsi564A will be available in June 2005 for less than $59 each in volume compared with $99 for the Tsi568A.
