Final answer:
The four desirable characteristics of a benchmark program are relevance, consistency, verifiability, and unbiasedness. The MIPS rate cannot be determined without the specific CPI values for instruction types.
Step-by-step explanation:
Four desirable characteristics of a benchmark program are:
Relevance: The benchmark should consist of workloads and scenarios that closely mimic the real-world applications and use cases the system is expected to run.
Consistency: It should provide consistent results across different runs to ensure reliability and comparability.
Verifiability: The results should be verifiable, meaning that independent parties can replicate the test and achieve similar results.
Unbiased: The benchmark should not favor any particular system or component but instead evaluate performance objectively.
To calculate the MIP rate of the machine described in the second part of the question, we would need the specific values for each instruction type's CPI and their respective mix percentage in the workload. Unfortunately, these details are not provided in the question. However, the MIPS (Million Instructions per Second) rate can generally be calculated by taking the total number of instructions executed, dividing by the total execution time, and then dividing by a million. Since we know the processor speed is 800 MHz, we could have used this information to calculate execution time if we had CPI data for each instruction type.
