  2. Add SEG and SEQ fields to current TYPE word e.g. OR'ing function. (NOT supported in R3)
  3. 1GbE support. (done)

Memory Controller :

  1. Add support for RMAP processor accesses e.g. for RMAP read data forwarding. (NOT done)
  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)

Rx Application :

  2. Upgrade to new RMAP (done)
  3. Use FFT App for demo purpose. (done)


Command Generator :

  1. Add new interface to RMAP processor e.g. parsing of RMAP and Data frames. (done)

Tx Application :

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


RMAP Processor :
