METHOD OF PREDICTING COMPUTER PROCESSOR PERFORMANCE AND METHOD OF ADJUSTING FREQUENCY USING THE METHOD

摘要

According to an embodiment of the present invention, a method for predicting a change in the performance of a computer processor according to dynamic voltage and frequency scaling (DVFS) comprises the steps of: calculating a stop state time (T_stall(f)) at the processor operating speed (f); and calculating the total run time (T_total(f)) based on the calculated stop state time, wherein the stop state time (T_stall(f)) is a duration when the calculation operation of the processor is stopped until a response comes back from the main memory of a computer.
