The Tundra Semiconductor Corporation (Tundra)
Tsi578
is a third
generation RapidIO switch supporting 80 Gbits/s aggregate bandwidth.
The
Tsi578
is part of a family of switches that enable customers to
develop systems with robust features and high performance at low cost.
The
Tsi578
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 Tsi568A
TM
Serial RapidIO Switch, the
Tsi578
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
over 64,000 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 Tsi578 supports both in-band serial RapidIO access and out-of-
band access to the full fabric register set through the I
2
C interface.

SERIAL RAPIDIO SWITCH
Benefits
• Scalability: Single solution for mesh,
fabric, and aggregated systems
• Performance: Improved system and
distributed processing performance
• Power: SerDes implementation for low
power solution
Typical Applications
The Tsi578 can be used in many embedded communication applications. It
provides chip-to-chip interconnect between I/O devices and can replace
existing proprietary backplane fabrics for board-to-board interconnect which
improves system cost and product time-to-market.

The Tsi578 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.
