1) (30 points) Assume you just purchased your favorite laptop that contains a quad-core CPU, with the clock speed (each core) of 2.0 GHz (G = 109). Assume you would like to execute a program with 1000 instructions on the laptop distributed among the cores. Furthermore, assume that each core is capable of executing 2 instructions in each clock cycle. a. What is the clock cycle time (each core) in nanoseconds? b. What is the execution time of the program (in nanoseconds)? c. In a perfect situation, what is the theoretical speedup of the multi-core CPU in comparison to a single-core CPU with the same architectural design? (showing the process mathematically in reaching your final answer may help you in answering part d) d. In reality, a multi-core CPU rarely achieves the linear (full) speedup expected. What is the best execution time of the program (on the quad-core) if the highest speedup of the quad-core CPU is 70% of its theoretical speedup (obtained in part c)
