ABSTRACT:
Provided is a method of reliably reducing power consumption of a computer, while promoting prompt compilation of a source code and execution of an output code. The method according to this invention includes the steps of: reading a code which is preset and analyzing an amount of operation of the CPU and an access amount with respect to the cache memory based on the code; obtaining an execution rate of the CPU and an access rate with respect to the cache memory based on the amount of operation and the access amount; determining an area in which the access rate with respect to the cache memory is higher than the execution rate of the CPU, based on the code; adding a code for enabling the power consumption reduction function to the area; and generating an execution code executable on the computer, based on the code.
