ÐInteger addition is one of the most important operations in digital computer systems because the performance of processors is significantly influenced by the speed of their adders. This paper proposes a self-timed carry-lookahead adder in which the logic complexity is a linear function of n, the number of inputs, and the average computation time is proportional to the logarithm of the logarithm of n. To the best of our knowledge, our adder has the best area-time efficiency which is …n log logn… CONTINUE READING
