Abstract
A dot product operator ( ) uses adder trees ( ) of L-1 adders and no multiplication circuits, where L is the length of the parallel dot product operator. Exclusive-or gates provide the function of multiplication by ±1, with the carry-in ports of adders ( ) being used to form the two's complement, resulting in an extremely efficient design in terms of area and power.
