• Adder (electronics) — In electronics, an adder or summer is a digital circuit that performs addition of numbers.In modern computers adders reside in the arithmetic logic unit (ALU) where other operations are performed.Although adders can be constructed for many… …   Wikipedia

• Adder-subtracter — In digital circuits, an adder subtracter is a circuit that is capable of adding or subtracting numbers (in particular, binary).Below is a circuit that does adding or subtracting depending on a control signal.However, it is possible to construct a …   Wikipedia

• Carry-lookahead adder — 4 bit adder with carry lookahead A carry lookahead adder (CLA) is a type of adder used in digital logic. A carry lookahead adder improves speed by reducing the amount of time required to determine carry bits. It can be contrasted with the simpler …   Wikipedia

• Carry look-ahead adder — A carry look ahead adder is a type of adder used in digital logic. It can be contrasted with the simpler, but usually slower, ripple carry adder ( see adder for detail on ripple carry adders ). A ripple carry adder works in the same way as pencil …   Wikipedia

• Brent-Kung adder — In electronics, an adder is a combinatorial or sequential logic element which computes the n bit sum of two n bit numbers. The Brent Kung adder is one of the more advanced designs, having a gate level depth of O(log 2(n)).Adding two n bit numbers …   Wikipedia

• Ling adder — In electronics, an adder is a combinatorial or sequential logic element which computes the n bit sum of two numbers. The family of Ling adders is a particularly fast adder and is designed using H. Ling s equations and generally implemented in… …   Wikipedia

• Carry-save adder — MotivationA carry save adder is a type of digital adder, used in computer microarchitecture to compute the sum of three or more n bit numbers in binary. It differs from other digital adders in that it outputs two numbers of the same dimensions as …   Wikipedia

• Serial binary adder — The serial binary adder is a digital circuit that performs binary addition bit by bit. The serial full adder has three single bit inputs for the numbers to be added and the carry in. There are two single bit outputs for the sum and carry out. The …   Wikipedia

• Carry bypass adder — A carry bypass adder improves the delay of a ripple carry adder.The two addends are split in blocks of n bits. The output carry of each block is dependent on the input carry only if, for each of the n bits in the block, at least one addend has a… …   Wikipedia

• Carry select adder — In electronics, an adder is a combinatorial or sequential logic element which computes the n bit sum of two n bit numbers. The carry select adder is simple but rather fast, having a gate level depth of O(sqrt n).The Carry select adder generally… …   Wikipedia
