Abstract
Techniques for transforming input operands to reduce overhead for implementing addition operations in hardware are provided. In one aspect, a method for transforming input operands of an adder includes the steps of: receiving a bit array of the input operands; replacing a duplicate signal (e.g., a signal that occurs twice) for a given bit k in the bit array with a single signal at bit k+1; reducing a number of occurrences of the signal on adjacent bits of the input operand, wherein by way of the replacing and reducing a transformed bit array is formed; and providing the transformed bit array to the adder.
