In this pipeline, one can see that the selection and shuffling units (PMXL, PMC) are the same as in the fixed-point unit. Unlike the fixed-point pipeline there is no lane reduction unit, so the lanes that you have at the input will also be there at the output. Another difference is that the post-accumulator is on two clock cycles. If the goal is to reuse the same accumulator over and over, only one fpmac per two clock cycles can be issued.
