What’s a daxpy?
Daxpy is a BLAS function, the most commonly used: “double precision A times X + Y”; see https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms#Level_1. It’s why hardware has FMA (a.k.a MAC) ops.

And when you write “cycle,” do you mean a clock cycle or a Mill instruction?
Absent stalls, Mill issues all instructions of one bundle (formerly described as “all operations of one instruction”, except people got confused by the terminology) in one clock cycle. So cycle and bundle (instruction) are equivalent.
