Note that if an integer summation were performed instead of a floating
point
summation, five partial sums would be generated and placed in
elements
59 through 63 since the functional unit time for the integer add
unit is 3 CPo
Assuming that the same registers are used as for the previous
example but that the registers now contain integer values, the last five
elements of V2 would contain the following values:
