Embodiment Construction

[0024] The specific implementation method is that the static compiler divides the code segment into three related code segments, which are respectively the running initialization code segment, the dynamic frequency modulation code segment and the running end code segment. Running the initialization code segment is to prepare for the following code to run; in the dynamic frequency modulation code segment, the operating system will optimize the frequency of the processor and main memory according to the relationship between the processor and the main memory, optimize the system energy consumption, and be able to The instructions in this code segment are divided into processor-related instructions and main memory-related instructions, and the requirement to obtain this code segment is that the two related instructions can run at the same time; the execution instructions in the end-of-run code segment must rely on dynamic The execution result of the FM code segment can be run. Thi...

Abstract

The invention discloses a method for optimizing operation frequency by combining static compiler and dynamic frequency-modulation technology. The invention comprises employing static compiler separation separating code segment into three related segments, which are the operating initialization segment, the dynamic frequency-modulation technology segment and the operating finishing segment; according to the relationship of the processor and the main storage in dynamic frequency-modulation, setting corresponding operating frequency of the processor and the main storage via the dynamic frequency management technology to save power. The inventive method is characterized in that it improves prior power saving technology which controls the power consumption of the processor and the main storage to lower power consumption when the system is operating.
