Question

a program consists of 1 million instructions. it executes a 4 ghz processor. each instructions takes on average 3 clock cycles. how long does the program execute for in seconds?

Answer 1

The program will execute for 0.00075 seconds.

Step-by-step explanation:

To calculate how long the program executes for, we need to find the total number of clock cycles required to execute all the instructions. Since each instruction takes an average of 3 clock cycles, the total number of clock cycles is 1 million instructions * 3 clock cycles per instruction = 3 million clock cycles.

Now, we can find the time duration by dividing the total number of clock cycles by the clock speed of the processor. The clock speed is given as 4 GHz, which means it can perform 4 billion clock cycles per second (4 GHz = 4 * 10^9 hertz).

Therefore, the program will execute for 3 million clock cycles / 4 * 10^9 clock cycles per second = 0.00075 seconds.
