| <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. | ||

| This documentation is provided for developers intending | ||
| to support RapidIO on new architectures, write new drivers, | ||
| or to understand the subsystem internals. | ||
