Hi Laura The ROACH does not have a direct 1Ge connection to the FPGA, any data must exit via the PPC if it is not going through the 10Ge links.
The ROACH2 however, has a 1Ge link directly to the FPGA. The yellow block has been completed and has been designed to act the same as the 10Ge links (basically the same interface, can be accessed from the PPC if needed, ARP table managed from PPC etc) except that the data rate is lower (8 bit data paths instead of 64 bit). We should be finalising these yellow blocks and making an announcement soon so that people who are interested can start designing for ROACH2.
