VHDL code for hamming distance calculation

[K.S.GANESH KUMAR]

hi,
can anyone send VHDL code for calculating hamming distance between two test vectors.
example :v1=1010100011 and v2=0101000111.
the hammindg distance is 6.
i need VHDL code for this hamming distance calculation.

Thanks.

Fresh out of hamming distance code. In fact, I am fresh out of ham. Guess it's time for groceries.

So I will do my own groceries, while you do your own homework. Okay then, sounds like a plan.

you can actually do this with a for loop. eg:

--pseudocode
d := 0;
for idx in v1'range loop
  if v1(idx) /= v2(idx) then
    d := d + 1;
  end if;
end loop;

If you use XST, you should see that it infers an adder tree in the synthesis report.

thanks sir..,suppose we have don't care bit(X) in the test vectors like v1=XX0011 and v2=X01001 means the operator(/=) not gives correct output sir.am doing xor operation sir..can u tell others methods sir.. and we have more vectors sir.(upto v20)
thanks sir.
