The Tsi574 Advantage
The Tundra Semiconductor Corporation (Tundra) Tsi574
TM
is a third
generation RapidIO switch supporting 40 Gbits/s aggregate bandwidth.
The Tsi574 is part of a family of switches that enable customers to develop
systems with robust features and high performance at low cost.
The Tsi574 provides designers and architects with maximum scalability to
design the device into a wide range of applications. Flexible port
configurations can be selected through multiple port width and frequency
options.
Building on the industry leading Tsi564A
TM
4/8 Port Serial RapidIO
Switch, the Tsi574 contains all the benefits of its predecessor plus
enhances the fabric switching capabilities through the addition of
multicast, traffic management through scheduling algorithms,
programmable buffer depth, and fabric performance monitoring to
supervise and manage traffic flow.
Embedded applications further benefit from the ability to route packets to
multiple endpoints through hierarchical lookup tables, independent unicast
and multicast routing mechanisms, and error management extensions that
provide proactive issue notification to the fabric controller. In addition, the
Tsi574 supports both in-band serial RapidIO access and out-of-band access
to the full fabric register set through the I
2
C interface.

The Tsi574 provides traffic aggregation through packet prioritization when
it is used with RapidIO-enabled I/O devices. When it is in a system with
multiple RapidIO-enabled processors it provides high performance
peer-to-peer communication through its non-blocking switch fabric.
