Abstract
The multiplier is one of the important elements in most of the digital processing system such as FIR filters, digital signal processors, and microprocessors etc. The speed of a system depends upon how a faster an arithmetic operations are performed within the structure for which mostly multiplication should be carried out at a faster rate which thus improves the system performance. The two important parameters of a multiplier are its area and speed that are inversely proportional.
Multipliers are of great significance in today’s Digital Signal processing applications like DFT, IDFT, FFT, IFFT, and ALU in Microprocessor. Wallace tree multiplier along with a Ripple Carry adder is hybridized and formed a hybridized multiplier which delivers high-speed computation along with the reduction in power consumption. Here, Wallace tree multiplier is used to increase the speed of addition and a Ripple Carry Adder is used for final accumulation. This hybrid multiplier produces better results in terms of speed and power than the conventional designs.
The proposed circuit is designed and the results are discussed in the paper. This proposed work is evaluated in the basic area, power, and delay.
