The development of power-efficient floating-point adders for two different frequency requirements is presented. Our goal is to design frequency and application specific adders that will provide the best overall system performance
For high-frequency applications, a fast 128-bit floating-point adder is designed and fabricated as part of the POWER6 binary floating-point unit in IBM 65nm SOI process technology. Efficient use of static circuits, careful balance of the look-ahead tree and optimal partition of the adder blocks enable the floating-point unit to operate beyond 5GHz with 1.1 V supply
For medium frequency applications, a power and area efficient 108-bit floating-point adder is implemented using IBM 65nm SOI technology. Careful balances of the adder structure and structure-aware layout techniques enable our adder to have a latency of 270ps at power consumption of 2 0mW with 1V supply
