2d FIR filter image filtering time

Hi,

I want to ask, how can I measure image filtering time of 2D FIR filter?

The pixels of image comes from frame buffer.

Thank You

    simulate and measure the time between sop of input and output will give you a good idea. it may be somewhat elastic, so you may see +/- a few clocks on average
