4.5. Logical Layer Modules

This section describes the features of the Logical layers, and how they integrate and interact with the Transport and Physical layers to create the three-layer RapidIO protocol. The following figure shows a high-level block diagram of the Logical layer, which consists of the following modules:
  • Concentrator module that consolidates register access.
  • Maintenance module that initiates and terminates MAINTENANCE transactions.
  • I/O slave and master modules that initiate and terminate NREAD, NWRITE, SWRITE, and NWRITE_R transactions.
  • Doorbell module that transacts RapidIO DOORBELL messages.
