Question

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 selection of software applications and system software. These specific programs are called “benchmarks”. We will test a set of processors using one such benchmark, and our selected software program is a compiler. The complier program is written using a high level language that will be translated to the Assembly Language instructions that are native to each processor. Next, the number of Assembly Language instructions needed will be counted and used in the equations, above, plus the recorded clock speed and CPU cycles used by the processor’s CPU (central processing unit).

You must implement the following:

1.You are to use pointers and a function named “performance” to measure the performance of a given processor as described, above. The performance function must be a void function (does not return a value).

2.Your code should read the input from a data file named “data.txt” which has the data organized in rows such that each row contains the input values of a specific processor, in this order: # clock cycles, CPU speed (clock rate) in Giga Hertz (1 Giga Hertz = 1 x 10⁺⁹ Hertz), and # instructions.

3.Your code should be general and continue reading the data file till EOF is reached.

4.Your code should be modular. The main function should contain only function calls.

5.The output of code should be saved to an output file named “results.txt” and should also be echoed to the display.

Here is a sample run for data file that has data for 2 processors:

To understand the first line of data, processor 1 has executed the complier program using 10 billion Assembly instructions and 7 billion clock cycles. Its processor speed (clock rate) is 4 Giga Hertz.

Can anyone help me with this question ??
