MIPSfp is a hardware co-processor that increases floating-point instruction execution by a factor of 2 compared to using a MIPSknights general-purpose CPU alone. For a data-compression application on an enhanced system having a MIPSknights chip and a MIPSfp chip, 5% of the total execution time is performed exclusively by MIPSfp and the remaining (100 - 5)% exclusively by MIPSknights.

Sought: Partial Credit 1: What speedup is achieved using MIPSip compared to an unenhanced system using MIPSknights alone?

Partial Credit 2: What percentage of the unenhanced system's execution time would be executed by MIPSfp?

Partial Credit 3: A MIPSknights chip sells for $5. What is the maximum price of MIPSfp in order to provide a performance benefit per dollar in an enhanced system, when compared MIPSknights alone?
