In these situations, the datapath can be up to 36 bits, allowing sufficient capacity for
bit growth or gain changes in the signal source without loss of precision, which is
useful in single precision block floating point applications. As shown in
the high-precision multiplier is performed in two stages. The sum of the results of the
two adders produce the final result:
Z[54..0] = P
