The LP-Serial Endpoint Core implements all of the functions are defined in the RapidIO Physical Layer LP-Serial Specification Rev. 2.2. Figure 1 illustrates the overall architecture of the core.The core integrates an IO Logical Layer Initiator that maps AXI4 transactions into RapidIO IO Logical request packets. The user interface consists of a 64-bit or 128-bit AXI4 slave interface.The core also integrates an IO Logical Layer Target that maps RapidIO IO Logical request packets into AXI4 transactions on the user interface. This user interface consists of a 64-bit or 128-bit AXI4 master interface.In addition to the RapidIO Physical layer functions, the core also includes Management Module that supports access to Physical, Transport, and Logical Layer CSRs either through maintenance transactions, or through the AXI4-lite Local Management Interface (LMI).
