Hi Sebastian,
Thank you for your contibution, the code looks good. Just a little comment for future performance improve, "fmov w12, s2" are expensive because data across Neon and Integer fields, especally it is inside the loop. There are also some deep-seated data organization and algorithm problems, for example, we spends many instructions for absCoeff[numNonZero], if we allow spare zeros inside of array, we will reduce many of instructions.
