Hi again, again! Now I have tried your code and mine on the Cygwin/x86
platform as well, and this time your code was more than two times slower
than mine.
So it seems like this:
sum += *tmp_coeff_ptr++ * *tmp_input_ptr++;
is often more optimal than this:
sum += coeffs[tap] * input[lag+tap];
Regards,
Johan
