<p>A dot product operator (30) uses adder trees (10) of L-1 adders and no multiplication circuits, where L is the length of the parallel dot product operator. Exclusive-or gates 12 provide the function of multiplication by ±1, with the carry-in ports of adders (14, 16, 18, 20, 32, 34, 38, 44) being used to form the two's complement, resulting in an extremely efficient design in terms of area and power.</p> |
