  • Abstract
    An efficient scheme for carry propagation in an ALU implemented in n-MOS technology is presented. An algorithm that determines the optimum division of the carry chain of a parallel adder for various data path sizes is developed. This yields an implementation of a fast ALU which due to its regular structure occupies a modest amount of silicon. The speed of the implementation described is comparable to the carry look-ahead scheme. Our method is based on the optimization of the carry path implemented in n-MOS technology but the results can be applied to other technologies.
