Implementation of Ripple Carry Adder Design for Optimal VLSI Performance

Abstract :

In the province of wireless receivers, biomedical equipment, and portable/mobile devices, the demand for Very Large Scale Integration (VLSI) systems that optimize space, minimize power consumption, and deliver high performance is dominant. At the core of these systems, adders play a pivotal role as the primary component of arithmetic units. This paper proposes a ripple carry propagate adder with a high-speed area-efficient. The two’s complement representation is employed for adding two numbers, a common practice in various systems dealing with n-bit input sequences. Microprocessors and digital signal processing use these carry adders. The carry output of every finished adder stage is useful as a carry input to the one behind it. This procedure is continued until the last complete adder stage is reached. Each carry output bit in an entire adder is therefore rippled to the next stage. An exact (forward) carry adder be linked with the proposed structure to generate hybrid adders with tunable accuracy levels. The practical implementation of proposed model is carried out using Xilinx ISE Design Suite 13.4, showcasing its feasibility for real-world applications.
