A program executes 3 billion instructions in the processor, the processor spends 2 cycles on each instruction and is operating at 3GHz. What is the execution time of this program?
+4 To calculate the execution time of the program, we need to determine the number of cycles required and divide it by the processor's clock rate. Given that the processor spends 2 cycles on each instruction and the program executes 3 billion instructions, the total number of cycles required would be:
Total Cycles = 2 cycles/instruction * 3 billion instructions = 6 billion cycles
Now, to calculate the execution time, we divide the total number of cycles by the processor's clock rate. The processor operates at 3GHz, which means it can perform 3 billion cycles per second. paybyplatema
Execution Time = Total Cycles / Clock Rate = 6 billion cycles / 3 billion cycles per second = 2 seconds
Therefore, the execution time of this program would be 2 seconds.
