7.
Consider three diff erent processors P1, P2, and
P3 executing the same instruction
set. P1
has a 3 GHz clock rate and a CPI of 1.5. P2 has a 2.5 GHz clock rate and a CPI
of 1.0. P3 has a 4.0 GHz clock rate and has a CPI of 2.2.
a. Which
processor has the highest performance expressed in instructions per second?
b.
If the processors each execute a program in 10
seconds, find the number of
cycles and the number of instructions.
c. We are
trying to reduce the execution time by 30% but this leads to an increase of 20% in
the CPI. What clock rate should we have to get this time reduction?
8.Assume a
program requires the execution of 50 × 106 FP instructions,110 × 106 INT
instructions, 80 × 106 L/S instructions, and 16 × 106 branchinstructions. The
CPI for each type of instruction is 1, 1, 4, and 2, respectively.Assume that
the processor has a 2 GHz clock rate.
a.
By how much must we improve the CPI of FP
instructions ifwe want the program to run two times faster?
b. By how
much must we improve the CPI of L/S instructionsif we want the program to run
two times faster?
c.
