Thank you for revealing the above info about the FU population in the current Mill Gold spec. I understand that it’s subject to change.

I take it that an lsFU is a load/store functional unit. An lsbFU sounds like a close relative of load/store, but what does the b in lsbFU stand for?


With the exception of floating point on the exu side, it looks like slot zero on both sides can perform any operation that any higher slot on the same side can do. Is there an underlying architectural reason for that? (Other than sim indicating that doing so helps performance?)
