Tundra Semiconductor Announces Mercury Computer Systems Sublicenses RapidIO Tsi578 MicroTCA Switching Module

    Mercury to Deploy Module with Tundra's RapidIO MSM for WiMAX, 3G LTE
    MicroTCA Systems

    CHICAGO, IL, Sept. 26 /CNW Telbec/ - WiMAX World 2007 - Tundra
Semiconductor Corporation (TSX: TUN), a global leader in System Interconnect,
announced today that the Company has sublicensed the Tundra Serial RapidIO(R)
Tsi578 MicroTCA(TM) Switching Module (Tsi578MSM(TM)) reference design to
Mercury Computer Systems. Mercury intends to manufacture and integrate the
Tsi578MSM into Mercury's MicroTCA-based Ensemble(TM) systems for WiMAX and LTE
wireless applications, in addition to video, military imaging, and signal
processing applications.
    "The Tsi578MSM provides the high-speed 10 Gbps RapidIO fabric backplane
interconnect and complements Mercury's Ensemble MicroTCA systems for
next-generation wireless applications," said Greg Tiedemann, Director of ATCA
Business Development at Mercury. "Combined with Mercury's broad range of AMCs
and enabling software, the Tsi578MSM is also ideally suited to low-latency,
high-performance commercial and military data plane applications."
    In May 2007, Tundra announced that the Company collaborated with Ericsson
to license a MicroTCA Switching Module. The module was originally designed by
Ericsson, and subsequently licensed to Tundra to accelerate the deployment of
Serial RapidIO-enabled MicroTCA systems.
    "This announcement is another significant milestone in the RapidIO
market, as we continue to see adoption of RapidIO technology for use in WiMAX,
and 3G LTE deployments," said Daniel Hoste, President and Chief Executive
Officer, Tundra Semiconductor. "Tundra and Mercury continue to work closely
together to deploy industry-leading RapidIO solutions. Leveraging the proven
Tsi578MSM, Mercury will accelerate their customer's time to market with a
scalable MicroTCA solution," continued Hoste.
