Upon review of the VHDL (AV-1147), I noticed that the bypass path does not have the same pipeline delay as the normal path. It would be better if they matched. However, an alternative means to achieving the bypass functionality, is to set the phs_inc to the max positive value. This has the net affect of multiplying the input data x1 and allows the data to pass through the normal pipeline delay path. Unfortunately, there is a non-zero impact signal processing wise, but it may be statistically so small that its impact can be considered negligible (application dependent).
