Problems solved by technology

However, because the program in the software is executed, there is a problem that the slow operation of the JVM is disturbing.
Although recent decisions about existing power management techniques have been enhanced by making them central to the operating system (OS), many traditional power management decisions are mere guesswork
[0010] Although the above methods may be able to achieve the result of reducing power consumption, but there is no way to comprehensively reduce the operating voltage of each processor in the system, so as to further reduce the power consumption of the system

Embodiment Construction

[0023] The invention discloses a Java accelerator power management system. In a nutshell, the power management system of the present invention manages the power by reducing the power of the main processor and increasing the power of the Java processor in the Java accelerator when the Java program is started. This process is reversed when the Java application is terminated.

[0024] In the following description, numerous details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without some or all of these details. In other instances, well known procedural steps have not been described in detail in order to unnecessarily obscure the present invention.

Abstract

A power management method is disclosed which provides power management for a hardware based Java accelerator. Initially, a Java mode signal is provided from a host processor in response to initiating a Java application. Thereafter, power to the host processor is reduced, and power to a Java processor is increased in response to the Java mode signal. Then, when execution of the Java application halts, a Java completion signal is generated from the Java processor, thus signaling the system to return control back to the host processor.

Description

technical field [0001] The present invention relates generally to hardware accelerated Java execution, and more specifically to power management involving master / slave Java acceleration environments. Background technique [0002] This application is related to U.S. Patent Application No. 09 / 565,679 (Attorney Docket No. VTI1P333), filed May 4, 2000, and entitled: "A Java Stack, Arithmetic Logic Unit and Using the Same Multiple Stack Points and Intelligent Subsystem Architecture for the Approach", which is hereby incorporated by reference in its entirety. [0003] This application is also related to US Patent Application No. 09 / 670,496 (Attorney Docket No. PHILP337), entitled: "System and Method for Verifying the Lower Upper Boundary of a Java Queue", which is hereby incorporated by reference in its entirety. Computer programming in today's world offers many high-level programming languages. Java, for example, has achieved widespread adoption in a relatively short period of ...
