THREAD PROCESSING METHOD AND THREAD PROCESSING SYSTEM

Title:

THREAD PROCESSING METHOD AND THREAD PROCESSING SYSTEM

Document Type and Number:

WIPO Patent Application WO/2012/144011

Kind Code:

A1

Abstract:

In the present invention, a first OS (1) dispatches a first thread to a first CPU. The first OS (2) compares the access frequency to shared resources of the first thread to a first threshold. The first OS (3) determines the dependence of the first thread and a second thread that is being executed by a second CPU. The first OS (4) alters the setting of a clock generating circuit in a manner so that the phase of the clock supplied to the first CPU and the phase of the clock supplied to the second CPU are opposite phase when it has been determined that the access frequency is greater than the first threshold and there is no dependence (x mark). The first OS (4) alters the setting of the clock generating circuit in a manner so that the frequency of the clock supplied to shared resources is twice the frequency of the clock supplied to the first CPU.
