IRJET- A Low Power Binary Square Rooter using Reversible Logic and Modified Non-Restoring Algorithm (original) (raw)
Square root computation is an important mathematical operation which has wide range of applications. The design of square rooter needs to achieve low power, low area and high speed. Often there can be a trade-off among the three metrics. As the current technology aims for low power, designs require major architectural modification. This paper presents a low power binary square rooter using reversible logic and modified non-restoring algorithm. It uses reversible logic to achieve low power. The binary square rooter is designed and implemented using RCSM (Reversible Controlled Subtract Multiplexer). For further development such as number of quantum cost, garbage outputs and the constant inputs , binary square rooter is implemented using SRG (Samiur Rahman Gate).Binary square rooter using non-restoring algorithm is designed using both SRG and conventional approach. Simulations are carried out using ModelSim software and the power is obtained using X-Power Analyser. The power obtained for SRG and conventional technique are compared.
