R2 -> R3 updates
RCVR
Tx Ethernet Interface :
- Add support for segmentation when data size > 1500 bytes. (NOT supported in R3)
- Add SEG and SEQ fields to current TYPE word e.g. OR'ing function.
- 1GbE support. (done)
Memory Controller :
- Add support for RMAP processor accesses e.g. for RMAP read data forwarding. (NOT done)
- 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 :
- Add new RMAP interface to application top. (done)
- Upgrade to new RMAP (done)
- Use FFT App for demo purpose. (done)
XMTR
Command Generator :
- Add new interface to RMAP processor e.g. parsing of RMAP and Data frames. (done)
Tx Application :
- Add new RMAP interface to application top. (done)
- Upgrade to new RMAP (done)
- Remove system controller, SPI, and LED control from Tx datapath (SPI and LED controls are relocated to Control Plane) (done)
- Support AWGN/SINE/MOD for demo purpose. (done, however MOD is NOT supported in R3)
Control
RMAP Processor :
- New block (done)
RF Control :
- SPI read/write support, and related changes RMAP (done)
Top RMAP :
- New RMAP definition and excel spreadsheet. (done)
- Support of Board level IO e.g. LEDs... (NOT supported in R3)
Top Address Decoder :
- address bit19-16 decoding to generate cs_cmn, cs_xmtr and cs_rcvr chip select signals. (done)
Top Data/Control Mux :
- RMAP data read support as shown in Figure 1 (done)
