The table below shows the number of instructions per processor core on a multi core processor as well as the average CPI for executing the program on 1, 2, 4, or 8 cores. Using this data, you will be exploring the speedup of applications on multicore processors.

Assuming a 3 GHz clock frequency, what is the execution time of the program using 1, 2, 4, or 8 cores?
