Question: is FADD a single-cycle floating point adder?

[zhanghongce]

I’m not sure if I understand it correctly. Please correct me if I’m wrong. Are there any registers in FADD? I understand that there is a near path and a far path, but if you expect everything to be done in a single cycle, then the timing (critical path) is always determined by the far path. In that case, it seems it does not make sense to have two paths.
