In a radix-4 Booth-encoded multiplier,each group of three
bits (a pair,along with the most significant bit of the previous
pair) is decoded into several select lines and driven across the
partial product row as shown in Figure 7 [4].Compression of
the sign-extension bits,represented by E,is achieved by first
merging the signs of the partial products,represented by S,
with the multiplicand.Their sum is then pre-computed as
shown in each partial product row.This removes the sign-
extension bits from the critical path of the compressor tree.S
is 0 if partial product is positive,otherwise it is 1.E is XOR
function of the multiplicand and the partial product.
