How to implement a FIR filter with the ALTSHIFT_TAPS megafunction

Kaz,

Thanks for the reply. Running the clock faster means that I will need to leave empty spaces in the shift register (i.e. if the tab distance is 3, then I enter my coefficients each one spaced with 2 zeros). Am I right?

My filters are very long and I need to be careful with the resources of the FGPA.

I have done more work on this, but apparently there is no free lunch. Either i leave empty spaces on the shift register or I need to use a lot of memory to store partial sums of the convolution process.
