[2 + 2 + 2 + 2] The Figure below shows the Arithmetic Pipeline. The inputs to the floating-point adder pipeline are two normalized floating-point binary numbers X = A x 2, Y = B x 25 Suppose that the time delay of the four segments in the pipeline are as follows: = 10 ns. t = 100 ns, tz = 70 ns, tz = 60 ns, and tų = 80 ns. The interface registers delay time ty - = Exponents а b I Mantissas B R Difference Segment 1 Compare Exponent By subtraction Align mantissas R HE Segment 2 Choose exponent Segment 3 Add or subtract mantissas R R Segment 4 Adjust Exponent Normalize result
