*** Tundra Semiconductor Demonstrates Next Generation VME
Technology
(January 19)

Tundra Semiconductor announced successful demonstration of 2eSST
technology using the Tundra Tsi148 VME-to-PCI/X Bus Bridge.

The Tsi148 implements the 2eSST protocol. The 2eSST protocol
allows streaming transactions and is capable of achieving
backplane bandwidth up to 320 Megabytes per second, an 8-fold
increase over conventional VME. This improvement is equivalent to
2.5Gb/s.

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 - in the
military, industrial automation, communications, storage and
medical industries - 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.

The Tsi148, a small and pin efficient device, complements
Tundra's current VME product line that includes the Universe II
VMEbus-to-PCI Bus Bridge and the SCV64 VME64-to-Host Processor
Bridge.

Early access partners will have access to Tsi148 alpha samples
before general availability, which is scheduled for mid-summer
2004. These partners will get a time-to-market advantage with
integration support from Tundra.
