Tundra Semiconductor and RMI Corporation Announce Interoperability of Tundra's RapidIO Switch with RMI's High Performance XLS Multi-core Multi-threaded Processor

    Serial RapidIO Switch and XLS Processor Combination Enables High-
    Performance 3G and 4G Wireless Systems

    CUPERTINO, CA and OTTAWA, Feb. 10 /CNW Telbec/ - 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, today announces the interoperability of Tundra's Tsi578(TM)
Serial RapidIO(R) Switch with RMI Corporation's (RMI) high-performance
multi-core multi-threaded XLS(R) Processor.
    By using the Serial RapidIO Development Platform (SRDP), that includes
the Tsi578 RapidIO Switch, with RMI's XLS Processor(R) 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,
    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 the 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(R) - 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(R),
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.
