5.2 A microprocessor has two internal units, an instruction fetch unit and an instruction execute unit, with fetch/execute overlap. Compute the overall pro-cessing time of eight sequential instructions, in each of the following cases. 1. T(F)T(E) = 100 ns for i = 1 to 8 2. T(F) 50 ns, T(E) = 100 ns for i = 1 to 8 3. T(F) 100 ns, T(E) = 50, 75, 125, 100, 75 and 50 ns for i = 1, 2, 3, 4, 5, 6, 7 and 8 respectively. where T(F) is the time to fetch the ith instruction and T(E) is the time to execute the ith instruction.
