The increasing importance of datapath circuits in complex System-on-Chips (SoCs) calls for special arithmetic optimizations. The goal is to automatically achieve the handcrafted results which escape classic logic optimizations. Some paper has been done in the recent years to infer the use of the carry-save representation in the synthesis of arithmetic circuits. Yet, many cases of practical interest cannot be handled due to the scattering of logic operations among the arithmetic ones - particularly in arithmetic computations which are originally described at the bit level in high-level languages such as C.
