I am trying to Implement 8 pt Radix 2 Butterfly DIF FFT on an ASIC
I have just finished preparing the logic how to do it .... I just wanted to know which are the best Adders and Multipliers that I could use in my butterfly ???
Adders and Multipliers should be more efficient - is the citeria
Thanksa lot!
if u r doing asic just write
assign c = a*b;
and give directive to the DC.
it will use the multiplier and adder u specified.
or if u use design ware foundation libraries and optimizing for speed booth recoded mul's and prefix adders are synthesized.
