Multiply and Add: Design a combinational circuit that computes P = XY +Q+R The inputs X and Y are 4-bit unsigned integers. The inputs Q and R are 8-bit unsigned integers and the output P is 10-bit unsigned integers.) Your design should use three levels of carry-save adders and a final ripple adder no larger than 6-bits. a) Using dot diagrams show the levels of the carry-save tree in the squares on the left. Label your circuit nodes in the corresponding rectangles on the right. 07 05 05 (30) (21) (20) (12) (10) (33) (01) (00) JOOX 200 Q. | Ro 08 06 04 02 01 00 S06 S04 20323.
