When used in combination with a RapidIO switching fabric device,
such as the Tundra Tsi500
TM
, the Tsi400 provides a seamless
PCI/X-to-PCI/X connectivity across a RapidIO architecture (see
Figure 2). Investments in current PCI and PCI-X applications, are
therefore maintained, while new intra-system interconnects can be
based on the faster and more reliable, RapidIO technology.
