[0046] see figure 1 , the first embodiment of a method for dynamic frequency conversion of a processor in the present invention specifically includes:
[0047] 101. Obtain the operation busyness of the input device;
[0048] In this embodiment, the input device is a medium of human-computer interaction, and the user performs an operation on the input device, and the input device converts it into an instruction and sends it to the terminal. The so-called operation busyness is a parameter representing the number of operations on the input device. The specific acquisition method will be described in subsequent embodiments.
[0049] 102. Calculate the CPU usage;
[0050] In this embodiment, the method for calculating the CPU usage rate belongs to common knowledge, and will not be described in detail.
[0051] 103. Calculate the busyness of the operation and the CPU usage using preset calculation rules to obtain an idle index value;
[0052] In this embodiment, the previously ...

[0056] see figure 2 The second embodiment of a method for dynamic frequency conversion of a processor in the present invention specifically includes:
[0057] 201. Establish a timer;
[0058] In this embodiment, the timer is established for the convenience of counting the number of times the user operates on the input device.
[0059] 202. According to the established timer, count the number of operations performed by the user on the input device per unit time, and record it as a busy operation;
[0060] In this embodiment, the number of operations performed by the user on the device per unit time is counted. For example, if the user faces the TV and presses the remote control button N times within M minutes, then the operation busyness is N / M, which can be It is represented by the busy factor S.
[0061] 203. Calculate the occupancy rate of the processor (ie CPU);
[0062] In this embodiment, the method for calculating the CPU occupancy rate belongs to common knowledge, ...

Abstract
Embodiments of the invention disclose a dynamic frequency conversion method and apparatus for a processor, so that the burden of a CPU can be effectively reduced, the running speed of a terminal can be increased, and the service life of the terminal can be prolonged. The dynamic frequency conversion method for the processor comprises: obtaining an operation busy degree of an input device; calculating an occupation rate of the CPU; performing calculation on the operation busy degree and the occupation rate of the CPU by using a preset calculation rule to obtain an idle index value; and judging whether the idle index value is less than a critical value or not, and if so, adjusting a main frequency of the CPU according to the idle index value.
Description
technical field [0001] The invention relates to the field of software, in particular to a method and device for dynamic frequency conversion of a processor. Background technique [0002] The human-computer interaction process is realized by the user inputting commands on the input device, and then the processor (CPU, Central Processing Unit) of the terminal receives the command, and then completes the operation. And when the processor is not receiving instructions, it is in an idle state. If the processor still maintains the operating frequency at this time, it will inevitably cause waste of resources. Contents of the invention [0003] Embodiments of the present invention provide a method and device for dynamic frequency conversion of a processor, which can effectively reduce the load on the CPU, increase the operating speed of the terminal, and prolong the service life of the terminal. [0004] A method for dynamic frequency conversion of a processor in an embodiment of...
