ADDITION WITH THREE PARALLEL CLA CIRCUITS

摘要

In this paper, a parallel version of the CLA addition algorithm will be introduced. In the presented algorithm three parallel CLA circuits are employed in the computation of the carries. The computations of the carries are equally divided among the three parallel CLA circuits. An octal, radix-8, logic is used in the parallel CLA algorithm. Despite the inclusion of the non-binary logic, the algorithm is completely realizable by binary gate. The parallel CLA algorithm and the traditional CLA algorithm are compared in terms of gate the delays.
