Efficient Squarer Design Using Group Partial Products
The partial product matrix (PPM) of a squarer is symmetric. To reduce the depth of PPM, it can be folded, shifted and rearranged. In this paper, we propose a squarer design method using partial product grouping method. The proposed squarers lead to up to 24.7%, 24.4% and 6.7% reduction in area, power consumption and propagation delay compared with conventional squarers.
