Problem 1:

a. If the 1998 version of a computer executes a program in 200 s and the version of the computer made in the year 2000 execute the same program in 150 s, what is the speedup that the manufacture has achieved over the two-year period?

b. To achieve a speedup of 4 on a program that originally took 80 s to execute, what must be the execution time of the program be reduced to?

c. A computer architect is designing the memory system for the next version of a processor. If the current version of the processor spends 40 percent of its time processing memory references, by how much must the architect speed up the new memory system to achieve an overall speedup of 1.2? A speedup of 1.6?
