Program consists of 16 instructions (I1, I2, I3, ...., I16). In which I6 is a unconditional branch instruction transfer the controls of I12. In the pipeline, branch target address will be available at the end of execute state. Each instruction spends the same amount of time in all the pipeline stages. The cycle time of the pipeline is 10 nsec.
What is the time (in nsec) required to execute the above program without using branch prediction?
