Abstract
This paper presents a fast 64-bit parallel carry look-ahead binary adder implemented in a 1 GHz research prototype 64-bit PowerPC microprocessor. Efficient use of dynamic compound gates enables implementation of the adder in just three stages of delayed reset dynamic logic. The computation uses only G (Generate) and P (Propagate), and the inverse of Carry is computed from G, P, and a strobe signal.
