Problems solved by technology

[0003] However, by controlling the maximum operating frequency of the computing unit to achieve the purpose of controlling the current of the computing unit, the performance of all computing units with the same clock source will be suppressed at the same time, resulting in poor user experience.

Abstract

The present invention relates to a control method for operation units. The method comprises: pre-determining a relative current value, and using the current value as a reference; then calculating a sum of current values of the practically running operation units according to a target frequency and a current temperature, comparing the sum of the current values with the relative current value used as the reference, and if the sum of the current values is smaller than the relative current value, using the target frequency corresponding to the sum of the current values as a candidate running frequency of the currently running operation units; and when the largest candidate running frequency is determined, setting the largest candidate running frequency as the running frequency of the currently running operation units. Namely, for a user, within a range of the relative current value, not only can running conditions of the operation units be met, so that the efficiency of the operation units is improved while current suppression is realized, but also running efficacy of the operation units cannot be suppressed, and thus, user experience also can be improved. Furthermore, the present invention provides a control system for the operation units.

Description

technical field [0001] The invention relates to the current control technology of a computing unit group, in particular to a control method and system of a computing unit with high efficiency. Background technique [0002] With the development of technology, the computing power of processors used in smart mobile terminals (such as mobile phones and tablet computers) is getting stronger and stronger. The processor contains more and more computing units in a very small physical package, which makes the problem of heat generation of the processor more and more concerned. For the current control of the computing unit in the prior art, the maximum allowable execution frequency and execution voltage of the computing unit are dynamically adjusted with reference to the temperature rise and the maximum current that can be supplied by the whole machine, so as to control the maximum current of the computing unit during execution. With the development of multi-computing unit groups (mu...
