== R2 -> R3 updates == 

=== RCVR ===
__Tx Ethernet Interface__ : [[BR]]
1. Add support for segmentation when data size > 1500 bytes. ''(NOT supported in R3)''[[BR]]
2. Add SEG and SEQ fields to current TYPE word e.g. OR'ing function. ''(NOT supported in R3)'' [[BR]]
3. 1GbE support. ''(done)''[[BR]]

__Memory Controller__ : [[BR]]
1. Add support for RMAP processor accesses e.g. for RMAP read data forwarding. ''(NOT done)''[[BR]]
2. Include FIFO to Rx App interface to prevent app data stalling when memory is being accessed by RMAP processor (3-4 clocks max.) ''(NOT done)'' [[BR]]

__Rx Application__ : [[BR]]
1. Add new RMAP interface to application top. ''(done)''[[BR]]
2. Upgrade to new RMAP ''(done)''[[BR]]
3. Use FFT App for demo purpose. ''(done)'' 

=== XMTR ===
__Command Generator__ : [[BR]]
1. Add new interface to RMAP processor e.g. parsing of RMAP and Data frames. ''(done)'' [[BR]]

__Tx Application__ : [[BR]]
1. Add new RMAP interface to application top. ''(done)''[[BR]]
2. Upgrade to new RMAP ''(done)''[[BR]]
3. Remove system controller, SPI, and LED control from Tx datapath (SPI and LED controls are relocated to Control Plane) ''(done)''[[BR]]
4. Support AWGN/SINE/MOD for demo purpose. ''(done, however MOD is NOT supported in R3)'' [[BR]]

=== Control === 
__RMAP Processor__ : [[BR]]
1. New block ''(done)''[[BR]]

__RF Control__ : [[BR]]

__Top Address Decoder__ : [[BR]]
1. address bit19-16 decoding to generate cs_cmn, cs_xmtr and cs_rcvr chip select signals. ''(done)'' [[BR]]

__Top Data/Control Mux__ : [[BR]]
1. RMAP data read support as shown in Figure 1 ''(done)''[[BR]][[BR]]
