pipelined multiplier doc
hi all
suppose we have a DSP block which include 10 multiply operand as follow:
(a0*a1 + a2*a3)(a4*a5+a6*a7)+(b0*b1+b2*b3)(b4*b5+b6*b7)
as u see , we must calculate 8 mul. at first then 2 mul. remaining.
so from speed view design plus trade of with area which method is better ?
i think pipeline multiplier give a high performance . what's ur idea?
if i am right , i would like to use spartan 3 MUL(18 bit * 18 bit or higher ) with pipeline method .can anyone give me some nice doc about pipeline multiplier in spartan 3 ?
