High Speed and Energy Efficient ALU Design using Ancient Computational Technique

An Arithmetic logic unit (ALU) is the heart of all digital microprocessors. All high performance systems such as FIR filters ,digital signal processors require a faster and energy efficient ALU to perform arithmetic operations with greater speed .Area and speed being the two conflicting constraints in VLSI design. This paper aims to find out the best trade off solution among both of them.While comparing the conventional ALU designs,Vedic ALU turns out to be the fastest amongst all.
