-FIFO and Buffer Interface Spec

-Buffer Interface Data Wires -- matches fifo36
-     DATA[31:0]
-     FLAGS[3:0]
-     Bit 0     SOP
-     Bit 1     EOP
-       If SOP=1 && EOP=1, OCC contains error flags
-     Bits 3:2  OCC[1:0] --> 00 = all 4 bytes
-                    01 = 1 byte
-                    10 = 2 bytes
-                    11 = 3 bytes
-
-fifo36 -->  {OCC[1:0],EOP,SOP,DATA[31:0]}
-       OCC same as buffer interface
-
-fifo19 -->  {OCC,EOP,SOP,DATA[15:0]}    
-       Doesn't fit well into BRAM, dist RAM ok
-       OCC = 1 means last word is half full
-          = 0 means last word is full
-
-fifo18 -->  {EOP,SOP,DATA[15:0]}
-       No half-word capability?  Should we drop sop instead?

-Control Wires - Data into FIFO
-       SRC_RDY_i    Upstream has data for me
-       DST_RDY_o    I have space
-                    Transfer occurs if SRC_RDI_i && DST_RDY_o
-       
-Control Wires - Data out of FIFO
-       SRC_RDY_o    I have data for downstream
-       DST_RDY_i    Downstream has space
-                    Transfer occurs if SRC_RDI_o && DST_RDY_i
