What is used to calculate the performance improvement of a computer architecture? What registers does the following code effect or change? mov ECX,5 rep movsb There may be more than one answer, please select all correct answers. For a given CPU, benchmarks will always give similar results. True False What are the two the main considerations driving advances in computer architecture? What single assembly instruction is the equivalent to the FORNEXT loop in a high level language? In memory, how are programs distinguishable from data? Data and programs look completely different in memory. They are always in completely separate areas of memory Data and programs look the same in memory and can be close together, since everything just a number. Programs are always in low memory and data is always in high memory. What is not a basic item that all CPUs can do?

Explanation / Answer

1. CPI is used to calculate the performance improvement

2. ECX and EDX

3. For a given CPU bencharmarks will not give similar results.

4. Performance and Cost

5. LOOP instruction in assembly

6. They are always in seperate areas of memory.


7. Graphics Output is not designed for every CPU
