In modern days, the server$-$side application development got a boost due to automation and all the JAVA programmers are now celebrating its $24$th birthday. Java has been one of the most popular language till date. With this background today we have to work on performance enhancement of a system and it is dependent on Processor Execution time. Now let$$s consider an Application development team that has written a java program which has $10,000$ Instructions in main function, $2000$ instructions in function F$1()$ and $500$ instruction in function F$2()$ and is executed on a system whose clock frequency is $3\mathrm{.}8$ Ghz$,$ The design also facilitates average cycles per instruction of $15.$ Calculate the CPU Time utilized to execute the program. Also what should be CPI Considered to reach the CPU Execution time to $30$ micro seconds
