If a system has an instruction that requires 10 clock cycles for fetching and 5 for execution at a frequency of 1.5 GHz, what is the total time taken to execute this instruction?
💡 Hint: Remember to calculate the cycles first and translate them into seconds.
Consider a scenario where an instruction takes varying cycles: fetching takes 8, 3 for execution, and another instruction fetch takes 7. Calculate the total cycles and the execution time if the CPU runs at 3.0 GHz.
💡 Hint: Calculate the total cycles first, then convert based on clock speed.
