    39 From Host, we can control the hardware (RMAP read/write operations) by sending RMAP ethernet frame messages. The packet classifier forwards RMAP specific frames to RMAP Processor, whereas data specific frames are routed to the Data processing functions. RMAP frames are parsed by the RMAP processor, where a register map read/write operation can be initiated.
     39From Host, we can control the hardware (RMAP read/write operations) by sending RMAP ethernet frame messages. The packet classifier classifies and forwards packets according to its
     40type :
     41 * RMAP packets  -> RMAP Processor
     42 * Data packets  -> Tx Buffer for APP processing
     43 * Other packets -> TCP/IP stack

    4145For RMAP read operations, read data must be forwarded back to Host. This is accomplished by following operations : [[BR]]
    42 1. RMAP Processor forwards read data to Rx Memory Controller. Note : shared access to Rx buffer with dataflow.[[BR]]
    43 2. Generate IP and Ethernet frame for transmission back to host. Some control header information are added in the
    44 payload section for Host RMAP read synchronization.[[BR]][[BR]]

     47 2. Generate IP and Ethernet frame for transmission back to host. Some control header information are added in the payload section for Host RMAP read synchronization.[[BR]][[BR]]
