Hello F-people!
i'm looking for a fast magnitude comparison for unsigned numbers
i need to know exactly which one of the mantissa (24 bits or 53 bits) is
the largest to feed the LOP with.
I was planing puting a comparator in the first stage of the adder, but
the obvious method is too long
(comparison from the last bit to the first). I wonder if such a
comparator exists with d<8...
In fact, i only need one bit result:
0 : A >= B
1 : A < B
Does anyone have an idea for it :) ?
