Embodiment Construction

[0013] In the various embodiments listed below, the same or similar elements or components will be denoted by the same reference numerals.

[0014] figure 1 It is a schematic diagram of an electronic device according to an embodiment of the present invention. Please refer to figure 1 , the electronic device 100 includes a processing device 110 and a control device 150 .

[0015] In this embodiment, the processing device 110 may be a central processing unit (central processing unit, CPU), and includes at least one core (core). The processing device 110 may receive a busy-waiting command (such as ZXPAUSE), wherein the busy-waiting command indicates that an operating system (operating system, OS) of the processing device 110 is in a busy-waiting state. For example, when the kernel code of the operating system of the processing device 110 encounters a busy waiting situation, the operating system, for example, generates a busy waiting command to the processing device 110 to indi...

Abstract

The invention relates to an electronic device and a power consumption control method thereof. The method comprises the following steps: receiving a busy waiting instruction , wherein the busy waiting instruction indicates that an operating system of the processing device is in a busy waiting state; obtaining a micro instruction of the busy waiting instruction according to the busy waiting instruction; generating a waiting enabling instruction according to the micro instruction, and obtaining a count value corresponding to the waiting enabling instruction; and according to the waiting enabling instruction, stopping sending the instruction to the processing device, enabling the processing device to enter an idle state, and starting the counter to enable the counter to start counting according to the counting value.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device and a power consumption control method thereof. Background technique [0002] Generally speaking, the processing of the kernel code of the operating system of the processor often encounters a situation that requires busy waiting, wherein the time of busy waiting is counted by a time stamp counter (time stamp counter, TSC) inside the processor . However, during the busy waiting process of the operating system, the core of the processor is still working non-stop, so the power consumption of the processor is still relatively high during the busy waiting process. Therefore, how to effectively optimize the power consumption of the processor in the busy-wait state will become an urgent research topic for various manufacturers. Contents of the invention [0003] The invention provides an electronic device and its power consumption control method, so as to effectively opti...
