1. What would be the execution time for a program containing 2,000,000 instructions if the processor clock was running at 8 MHz and each instruction takes 4 clock cycles?

2. A smart architect re-implements a given instruction-set architecture, halving the CPI for 50% of the instructions, while increasing the clock cycle time of the processor by 10%. How much faster is the new implementation compared to the original? Assume that the usage of all instructions are equally likely in determining the execution time of any program for the purposes of this problem.
