     8R3 architecture consists of following modules :
     9
     10 * '''Ethernet Port''' - Ethernet framing function, [[BR]]
     11    * Rx - receives ethernet frames from Host. Performs CRC checking, and forwards error free payload to packet processor.
     12    * Tx - transmits ethernet frames to Host. Generates Ethernet header and CRC, IP payload is provided by packet processor.  [[BR]]
     13
     14 * '''Packet Processor''' - IP layer processing[[BR]]
     15    * Packet classification - RMAP, Data, and other (such as ARP and DHCP packets)
     16    * UDP is used for board level communication e.g. RMAP and Data packets
     17
     18 * '''APP''' - User specific application [[BR]]
     19   
     20 * '''RF Port''' - DAC/ADC interfacing [[BR]]
     21
     22 * '''Control Plane''' - RMAP and RF control [[BR]]
     23
     24 * '''Timing Control''' - system wide clock control using clock enables [[BR]]
     25
     26From 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
     27type :
     28 * RMAP packets  -> RMAP Processor
     29 * Data packets  -> Tx Buffer for APP processing
     30 * Other packets -> TCP/IP stack
