Tundra Tsi578 RapidIO Switch Interoperates With RMI XLS Processor

Tundra Semiconductor Corporation (TSX:TUN), a leader in System Interconnect, and RMI Corporation, a leading provider of high-performance processors for communication and media rich applications, announces the interoperability of Tundra’s Tsi578[tm] Serial RapidIO® Switch with RMI Corporation’s (RMI) high-performance multi-core multi-threaded XLS® Processor.

By using the Serial RapidIO Development Platform (SRDP), that includes the Tsi578 RapidIO Switch, with RMI’s XLS Processor® evaluation platform, Tundra and RMI have successfully completed testing for interoperability between their two products. The comprehensive testing validates that the Tsi578, with multi-cast capability, and RMI’s multi-core and multi-threaded XLS Processor are interoperable and can be quickly deployed as a turnkey solution in wireless infrastructure applications such as WiMAX, WCDMA, TD-SCDMA, and LTE.

Tundra’s broad portfolio of RapidIO switches address designers’ requirements for low interconnect processing overhead, power consumption and latency, as well as facilitating high signal integrity board layout requirements. Tundra’s RapidIO switches offer a broad feature set including: field proven port flexibility supporting mixed port widths at up to 10 Gbps data speeds, hardware multi-cast, supervised traffic flow for increased performance and fabric management, and enhanced SerDes for the lowest power switch solutions available today. Tundra’s Tsi578 was the first switch in the market to achieve the RapidIO Interoperability Lab’s device interoperability level (DIL) certification in 2007.

“Tundra provides customers with a broad portfolio of RapidIO products that offer the highest performance and reliability with industry’s lowest power consumption. Tundra is committed to the interoperability of our switches with every endpoint within the extensive RapidIO ecosystem,” said Tracy Richardson, vice president of marketing, Tundra Semiconductor. “The successful interoperability testing between Tundra’s Tsi578 and RMI’s XLS Processor offers a high performance processor/switch option for wireless infrastructure OEMs. Designers of these systems can be confident that this solution can be designed-in efficiently and will deliver the reliable performance and throughput required to get their systems to market faster,” continued Tracy.

“RMI is excited to have successfully completed our interoperability testing with the Tundra Tsi578. This will provide existing and new XLS customers the assurance that new designs using both devices can be implemented quickly and reliably, to offer the highest performance for wireless infrastructure designs. With no additional bridge logic between the XLS Processor’s RapidIO interface and Tundra’s RapidIO Switch, our customers are guaranteed a dependable, ready to implement solution,” said Mark Litvack, director of business development, RMI.

The XLS Processor family utilizes up to four MIPS64® – cores with up to sixteen fine-grain hardware threads and operates at up to 1.3GHz. RMI’s multi-core multi-threaded technology provides the ultimate in performance. The XLS Processor family includes an Autonomous Security Acceleration Engine®, which allows the processor to perform application processes while simultaneously encrypting/decrypting data that the application needs. This results in ultra-efficient processor utilization. I/O on selected XLS Processors includes multiple Gigabit Ethernet ports, XAUI ports, and a native Serial RapidIO interface configurable in both x1 and x4 mode. The XLS Processor family accelerates packet-oriented applications essential for security appliances, wireless access points and switches, ATCA and AMC service cards, secured wire-line routers and switches, telecom media gateways, radio controllers and network signaling products. These vertical segments demand more processor performance and features with each generation of product, but the system power remains fixed. The XLS Processor family advances end-product evolution by providing the performance and features required, while remaining within a low power envelope.
