  • Carry skip adder with independent carry-in and carry skip paths
    Patent number: 5337269
    Abstract: A carry skip adder uses independent paths for propagating a skip carry bit and a carry-in bit. Propagation of the carry-in bit is inhibited during a first portion of the clock cycle to prevent spurious carry-in signals from affecting the operation. During this period, other logic functions may be performed, including calculation of the propagation bits and generate bits for each adder block.
