The runtime also turns all configurations of the device on and allows all configurations to operate at maximum processing power. In this way, when the traffic volume is not too high, the device processing capacity is excessive.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:

FIG. 1 is a schematic diagram of a method for controlling energy consumption of a function board according to the embodiment, including:

101: The monitoring module on the function board periodically samples the current load and processing capability of each processor on the board, and sends the current load value and processing capability value of each processor obtained by the sample to Scene judgment module;

The monitoring module can save historical load data for the most recent period of time to predict the load change trend, and use load forecasting as an auxiliary basis to make the energy saving strategy more accurate. Save History The length of the load data and the step size can be configured, such as saving every 10 minutes in the last 24 x 8 hours. The forecasting method of the load change trend may be: for example, using the historical load data of last Saturday as the load forecast for each time period of the Saturday, or plotting the historical load data into a curve according to the two-dimensional coordinates of the time and the load size to represent the change trend.

Action

Examples of the judgment conditions related to the period T1 are as follows:

Processor Down-Frequency: The processor is not operating at the lowest operating frequency and also calculates the lowest frequency that is dropped if the processor's processing power is greater than the processor's current load.

Processor Off: The processor has been operating at the lowest operating frequency and also counts the number of cores that were shut down if the processor's processing power is greater than the processor's current load.
