Multiplication is an arithmetic operation that has a meaningful impact on the performance of several real-life applications, such as digital signal and image processing. Analysis and comparison of different types of fixed-point multipliers such as Wallace tree, array, and Booth-2 with truncated and non-truncated versions were included in this design. Fixed-point multipliers were used to design floating-point multipliers through a hardware description language. As a result, area and speed values

Wallace tree floating-point multiplier required the smallest area and the shortest delay. The 8-bit versions of fixed-point multipliers were physically synthesized, using the Alliance tools, to obtain the layout of the circuits. The integrated circuits were successfully fabricated in a 0.5-μm CMOS technology.
