A study of performance comparison of digital multipliers using 22nm strained silicon technology

Multiplication is one of the most important fundamental operations in applications such as Digital Signal Processing and in ALU of the microprocessors. Since multiplication dominates the execution time and power consumption of most of the digital signal processing applications, high speed and low power multipliers are essential for next generation processors. This paper presents a detailed study of performance comparison of different types of multipliers such as Array Multiplier, Carry Save Multiplier, Wallace Tree Multiplier and Baugh Wooley Multiplier. The simulations were performed using 22nm predictive technology model with a supply voltage of 0.8V. Results show that baugh wooley multiplier is the fastest multiplier with the least delay.
