Consider that you have a code of 400,000 instructions which is executed using a 16 stages pipeline. It is expected that 20% of the instructions will cause exception 1 and 30% that will cause exception 2. In order to handle the exception 1, there is an exception handler which is using 20 cycles to execute (includes the flushing and reloading of the pipeline and the actual handling of the exception). The handler for the exception 2 runs for 10 cycles (includes the flushing and reloading of the pipeline and the actual handling of the exception). The pipeline frequency is 2.5 GHz i) How many cycles does it take to execute the code? ii) What is the average CPI for this code? iii) How long does it take to execute the code?
