POWER SAVING METHOD, PROGRAM, AND PROGRAM EXECUTION SYSTEM OF INFORMATION PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a technique for reducing power consumption by lowering a clock frequency in an idle period generated as a result of scheduling without decreasing a program execution speed by utilizing an analysis result of profile information especially in a multicore environment.

SOLUTION: A task for program execution inputs an intermediate code or a native code to execute a program and extracts "profile information" consisting of "execution time points" for every program blocs. Next, a task for program compiling inputs an intermediate code and "profile information", analyzes the profile information to output "power saving scheduling information" of compile processing, and performs the compile processing by using the "power saving scheduling information". The task for the program execution utilizes the native code generated as the result of the compile processing.
