<title>Introduction</title>
<para>
RapidIO is a high speed switched fabric interconnect with
features aimed at the embedded market. RapidIO provides
support for memory-mapped I/O as well as message-based
transactions over the switched fabric network. RapidIO has
a standardized discovery mechanism not unlike the PCI bus
standard that allows simple detection of devices in a
network.
</para>
<para>
This documentation is provided for developers intending
to support RapidIO on new architectures, write new drivers,
or to understand the subsystem internals.
