You have a program that executes on a certain processor in 200 seconds. Switching to a new processor with a redesigned floating point unit will improve the execution time of the floating point portion of the program by a factor of 4.
The program currently spends 30% of its execution time on executing floating point instructions.
What is the exection time on the new process?
How much faster does the code execute on the new processor than on the old one?
