Given a processor with a clock speed of 3GHz, determine the execution time for a program that executes 2.5 billion instructions with an average CPI of 4.
💡 Hint: Make sure to convert GHz to time properly before calculating execution time.
A new architecture is proposed, which promises to reduce CPI from 5 to 2 and reduce the instruction count by 30%. If the original execution time was 4 seconds, calculate the new expected execution time.
💡 Hint: Account for the reductions properly, and apply changes sequentially to ensure accuracy.
