An instruction cycle comprises 4 steps; fetch (F), decode (D), execute (E), and write back (W), where all steps require 1 clock cycle except the execute step, which takes 2 clock cycles. Assume 1 clock cycle = 10 ns. a) b) Sketch the space time diagram to execute five (5) instructions. Executing the instruction as in Q35(a) may produce Hazard. List 2 (two) possible solution to overcome the problem. Calculate the total execution time needed by the pipelined computer to execute a C++ program having 3000 instructions. c)
