Hello,

I would like to know if it is possible to implement a 262144-tap FIR filter in a Stratix V?

The input rate is 200kHz

The input resolution is 18 bits

The coefficient resolution is 18 bits.

Thanks for your help and advices!

Cheers!

A bit too drastic. But if you run your clk at 360MHz then you can have time folding of 360/.2 = 1800 hence you will need

262144/1800 = 146 multipliers
