A pipeline with 18 stages runs a program TEST having 5,076 instructions. Branches comprise 17 percent of the instructions, and the "branch not taken" prediction holds for all branch instructions. The clock cycle time for the pipelined processor is 18ns and each stage of the pipelined processor takes one clock cycle. Calculate the execution time of the program. Also calculate the speed-up factor of the pipelined processor compared to a non-pipelined processor.
