A program executes 10 billion instructions. It executes on an Intel processor that has an average CPI of 1.5 and a clock frequency of 2 GHz. How many seconds does the program take to execute? What is the cycle time of this Intel processor? Assume that an AMD processor takes 6 seconds to execute the program. What is the speedup provided by the Intel processor, relative to the AMD processor
Design and implement a C Language program that measures the
performance of given processors.
There are several metrics that measure the performance of a
processor. We will be using the following 3 measures:
1.CPI (clock cycles per instruction) = #clock cycles
/#instructions
2.CPU execution time = #instructions x CPI x clock cycle time
.
cylce time = 1/CPU clock rate in hertz units
3.MIPS (mega instructions per second)= #instrucrions/ CPU X
1000000
Typically, processors’ performance is measured using a wide...
