in practice other adder structures can be used as the basis for the variable-time
case.
The redundant adders have a constant delay, independent of the adder width.
Since this constant is quite low (between one and two full-adders, for the radix-2
case), these adders are significantly faster than those for conventional represen-
tation.
With respect to the area, we use as measure the number of cells. To take into
account the effect of the added complexity introduced by using a fast radix-2 m
module, we consider that the area of an m-bit module has a complexity
km m
times
the complexity of the radix-2 module. For the case of the ...
