Research direction

Start with Rocket-Chip-RoCC/src/main/scala/tile/LazyRoCC.scala and inspect how its existing 64-bit memory interface is connected to the accelerator. Determine whether the requested 128-bit memory transfer is supported and what interface or example would be needed; done should mean a defined 128-bit path or a clear documented limitation.
