Design and analysis of 16-bit Full Adder using Spartan-3 FPGA

The carry lookahead adder is the highest speed adder nowadays. In this paper, a new method for modifying the carry lookahead adder is proposed. Based on the analysis of gate delay and simulation, the proposed modified carry lookahead adder is faster than the carry lookahead adder.

COMPARATIVE ANALYSIS OF 32 BIT CARRY LOOK AHEAD ADDER

A look-ahead carry adder circuit has multiple stages that are grouped into a carry generation blocks. The size of one of the carry generation blocks is three stages. There may be other carry generation blocks that are of a size that is a whole number multiple of three stages. In an embodiment, the look-ahead carry adder has only one critical path.

CHAPTER 4 PARALLEL PREFIX ADDER 4.1 INTRODUCTION VLSI Integer adders find applications in Arithmetic and Logic Units (ALUs), microprocessors and memory addressing units. Speed of the adder often decides the minimum clock cycle time in a microprocessor. The need for a Parallel Prefix Adder (PPA) is that it is primarily fast when compared with a ripple carry adder. PPA is a family of adders

Design of Carry Look-Ahead Adder Using Reversible Logic Gates

The carry-lookaheadis a fast adder designed to minimize the delay caused by carry propagation in basic adders. It utilizes the fact that, at each bit position in the addition, it can be determined if a carry with be generated at that bit, or if a carry will be propagated through that bit. We have used domino logic for improved performance. Input/Output Input • Two 16-bit numbers = 32 inputs

Binary Adder (Asynchronous Ripple-Carry Adder) A binary adder is a digital circuit that produces the arithmetic sum of two binary numbers. A binary adder can be constructed with full adders connected in cascade with the output carry form each full adder connected to the input carry of the next full adder in the chain. The four-bit adder is a typical example of a standard component.It can be
