 * @section Introduction
 *
 * @subsection xxx Overview
 *  RapidIOTM is a non-proprietary high-bandwidth system level interconnect. It is 
 *  intended to offer giga-byte per second performance levels for chip-to-chip and 
 *  board-to-board communication. Its layered architecture, allows a highly 
 *  scalable interconnect capable of future enhancements.
