Tundra Releases Industry's Highest Performance PCI/X-to-VMEBUS Bridge

7/14/2004 - Tundra Semiconductor (TSX:TUN), the leader in System Interconnect, announced the production status and general availability for the industry's first PCI/X-to-VMEBus bridge, the Tundra Tsi148TM. The Tsi148 is the next generation VME component in Tundra's VMEbus System Interconnect product portfolio. This high performance device was collaboratively developed with Motorola Computer Group, a division of Motorola Inc., as part of the industry's VME Renaissance. Tundra worked closely with early access partners during the evaluation and testing stages of product development. The device has been released to production and will be available to all customers in August 2004. "General availability of the Tundra Tsi148 to is a key milestone in the VME Renaissance program," said Jerry Gipper, Director, Marketing, Motorola Computer Group. "It also reinforces Tundra's ongoing commitment to the VME market." Tundra's VME system interconnect devices are used by the industry's leading single board computer vendors and OEMs. These companies serve the telecommunications, military, aerospace, industrial automation and medical markets.

The Tsi148 delivers the bandwidth, performance and reliability that embedded systems customers require for their next generation VME applications. The Tsi148 is the industry's only PCI/X-to-VMEbus bridge, delivering a sustained transfer rate of 305 MB/s. The PCI/X interface complies with the PCI-X 133 MHz specification; provides superior bus efficiency; and can handle a number of streaming transactions while eliminating potential system bottlenecks. Fully backward compatible with legacy VMEbus systems, the Tsi148 PCI/X-to-VMEBus bridge preserves customers' current VME infrastructure investments while enabling them to bring their next generation products to market. "Our VME customers have demonstrated a high level of interest in the Tsi148," said Tim Warland, Tundra VME Product Manager. "They have told us that the Tsi148 has the right feature set at the right time for them."

"Tundra is the world leader in VME interconnect technology with more than 10 years experience in providing VME solutions and technical support to the embedded systems industry," said Rick O'Connor, Tundra Chief Technology Officer. "We work closely with our VME customers to ensure our products deliver the performance and functionality they require and to ensure we continue to supply superior levels of customer support."

The architecture of the Tsi148 maximizes PCI/X transactions for VME applications. It has a number of features that optimize bus utilization and overall board performance. Features of the device include:

The Tsi148 provides an increase in overall processing capability on legacy backplanes, while transparently enabling the high-performance distributed processing that new applications demand. The Tsi148 bridges PCI or PCI-X on the local bus to the VMEbus. It eliminates performance bottlenecks by operating as a peer with other devices on the local bus. This can reduce the total number of bridges that VMEbus product vendors and end-users require for bandwidth management on the host card. On the system interface, the Tsi148 operates in master or slave mode for traditional VME, 2eVME and 2eSST transactions. These protocols are industry standards developed by the VMEbus International Trade Association (VITA) of which Tundra is a member.

The Tundra Tsi148 PCI/X-to-VMEBus bridge will be available through Tundra's world-wide distribution network in August 2004. Documentation including ordering information, user manuals, reference schematics and software drivers will be available at www.tundra.com on July 19, 2004.
