Meaning of parameters in perfsys

Hi,
I just started the perfsys tool to measure the performance of the various FIR routines. However, I have some problems to interprete the results.
The CSV output for the ippsFIR_32fc() routine lists 3 different parameters. The first parameter parm1 is the tap len. But what are the other two parameters parm2 and parm3 with values of 1 or 2, respectively? There is nothing about them in the manual.
Any help would be appreciated.

Regards,
Axel

Hello Alex,

there is comment from our expert:

- for parm2 and parm3 means single-rate FIR

1 or 2 for these parameters means UpFactor & DownFactor for multi-rate FIRs (one processing function ippsFIR but two different ippsFIRInit functions SR and MR it is mentioned in the manual)

Regards,
Vladimir
