Description

Component power consumption estimation method based on business function
Technical Field
The invention relates to the technical field of component power consumption estimation of business functions, in particular to a component power consumption estimation method based on business functions.
Background
The temperature affects the service life of components in the electronic equipment, the service life of the components is seriously shortened at an overhigh temperature, and in order to improve the service life and the reliability of the electronic equipment, the electronic equipment must be reasonably thermally designed to ensure that the temperature of the components is not overhigh during the operation. Among them, the power consumption of the components determines the amount of heat generated by the components, and has a great influence on the thermal design of the electronic device. The accurate estimation of the power consumption value of the components is helpful for providing reasonable thermal design for electronic equipment, and the service life and the reliability of the equipment are improved.
However, in the prior art, a method for estimating power consumption of a processor was invented, as disclosed in application No. 201710349124.4. The method involves the analysis of the machine code instructions of the processor, needs to write a corresponding analysis program, and is very complex to implement. For non-universal chips such as switching power supply chips and SoC, the method cannot be implemented at all. The invention patent with application number 201310399718.8 proposes a method for determining the power consumption of components by using simulation technology. The method comprises the steps of testing a temperature cloud picture of an actual circuit board, adjusting the power consumption value of a component simulation model until the temperature cloud picture of a thermal simulation model and the temperature cloud picture of the circuit board meet preset conditions, and obtaining the power consumption value of the component simulation model. The method utilizes the existing electronic products and thermal simulation technology to reversely derive the power consumption of the components, and aims to provide reference for designing the electronic products in the future. However, the power consumption value of the component is related to the service function operated by the component, and the more complex the service function is operated, the power consumption will inevitably increase. If the service operated by the components is not considered, the power consumption value obtained by the method is used as a reference basis for designing future electronic products, and a larger error is inevitably brought.
