  2. Carry-lookahead adder - Wikipedia

    en.wikipedia.org/wiki/Carry-lookahead_adder

    Carry-lookahead logic uses the concepts of generating and propagating carries. Although in the context of a carry-lookahead adder, it is most natural to think of generating and propagating in the context of binary addition, the concepts can be used more generally than this.

  3. Lookahead carry unit - Wikipedia

    en.wikipedia.org/wiki/Lookahead_carry_unit

    A lookahead carry unit (LCU) is a logical unit in digital circuit design used to decrease calculation time in adder units and used in conjunction with carry look-ahead adders (CLAs). 4-bit adder [ edit ]

    en.wikipedia.org/wiki/74181

    Multiple 'slices' can be combined for arbitrarily large word sizes. For example, sixteen 74S181s and five 74S182 look ahead carry generators can be combined to perform the same operations on 64-bit operands in 28 nanoseconds (36 MHz). Although overshadowed by the performance of today's multi-gigahertz 64-bit microprocessors, this was quite ...
