2) Calculate the Difference functions for the function below, conclude the difference Engine Rule: =

3) One of the Main approaches studies in Computer Architecture is Pipelining, explain how does pipelining improve performance?

Amdahl’s LAW

4) Suppose that we want to enhance the execution time used for web serving, two designs have been proposed, show which one is better

Design 1: Use a new processor 15 times faster than the original processor, assuming that the original processor is busy with computation 50% of the time and waiting for the I/O 50% of the time.

Design 2: Use a new Processor 20 time faster. While the processor is 30% of the time busy with the computation and 70% waiting for the IO

5) A program spends 80% of its time doing addition instructions.

a. How much faster does the program run If the addition operation is sped up by a factor of 16 (Answer should be in the format: the program is X times faster.” And show your work)

b. What the Max of Speed up we can gain from this?

6) Analysis: Read the research paper portion below then using Moore’s and Amdahl’s law, write a reflection about which solution would you implement as a computer architect and why:
