    2. I'M ADMIN
      FORMULA FOR SPEED OF NON-PIPELINED AND PIPELINED RATIO:

Speed Up (S) =Non-pipelined execution time/Pipelined execution time





Pipeline Execution Time

= Maximum delay due to any stage + Register Delay

= Max { 60, 50, 90, 80} + 10 ns

= 90 ns + 10 ns

= 100 ns



Non-pipeline execution time for one instruction

= 60 ns + 50 ns +90 ns + 80 ns

= 280 ns



Speed up

= Non-pipeline execution time / Pipeline execution time

= 280 ns / 100 ns

= 2.8
