Question about FIR filter outputs

Hi, I designed FIR filter and I try to undestand why the number of output samples is different from the input? It lacks 2-3 samples. Thank you for your help.

On each rising edge of ast_source_valid (enable output), I write the result in file.

ex: I have a FIR filter with 16 coefficients. 5000 input samples with an enable => 4997 output samples. Why 3 missing samples?

If I want all my samples out, how do I do? I find nothing about it in the documentation.

Thanks
