Một chương trình thực hiện 3 tỷ lệnh trong bộ xử lý, bộ xử lý dành 2 chu kỳ cho mỗi lệnh và đang hoạt động ở tốc độ 3GHz. Thời gian thực hiện của chương trình này là gì?

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?

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.
