### "Faster and energy-efficient signed ..." refers background or methods in this paper

...The variable size of adder blocks always leads to faster performance than a fixed-size block adder [2, 17]; we, therefore, break down the ripple of gates in the BEC into variable-size groups according to the log 2 nmethod....

...In recent trends, the column compression multipliers are popular for high-speed computations due to their higher speeds [1, 2]....

...Once each part of the partial products has been reduced to height of one bit column, we get the final partial products as follows: p0[10] p0[9] p0[8] p7 p6 p5 p4 p3 p2 p1 p0 p1[15] p1[14] p1[13] P1[12] p1[11] p1[10] p1[9] p1[8]....
