Video rate dual port RAM filter question

--- Quote Start ---

Hello All,

A video rate FIR filter needs to be constructed, 31 taps x 12 bits. Also, NIOS needs to be able to update the coefficients on the fly.

Video will be sampled at clock rate, so all of the coefficients need parallel access.

The coefficient array is going to be symmetrical, so can be folded back to 16 elements(?).

Any better implementation suggestions other than making 16 x 12 bit individual dual-port RAM slices ?

Thanks,

Mark

one option is using registers (16x12) if you can afford it.

The other option is to concatenates sets of coefficients together so you use one address and split up the coeffs back.
