Question

Consider a processor with a clock rate of 2 GHz and an average CPI of 2. suppose the processor executes a program in 10 second.

what is the number of cycles executed by this processor during the program?

Answer 1

To calculate the number of cycles executed by a processor, multiply the clock rate by the execution time and the average CPI.

Step-by-step explanation:

With a clock rate of 2 GHz, an execution time of 10 seconds, and an average CPI of 2, the processor executed 40 billion cycles. The correct answer is option to calculate the number of cycles executed by a processor during a program, we use the formula: total number of cycles = clock rate (in hertz) × execution time (in seconds) × average CPI. Given a clock rate of 2 GHz, which is 2 × 109 hertz, an execution time of 10 seconds, and an average cycles per instruction (CPI) of 2, we have:

Total number of cycles = clock rate × execution time × CPI
= 2 × 109 hertz × 10 seconds × 2
= 4 × 1010 cycles

So, the processor executed 40 billion cycles during the 10-second program execution.
