On-chip power consumption management method, electronic device and storage medium

Abstract

The invention discloses an on-chip power consumption management method, an electronic device and a storage medium, comprising: acquiring first power consumption prediction information of instructions of multiple single cores within a prediction window; single cores according to the local first power consumption prediction information Determine the first warning information; determine the second warning information and power consumption control information according to multiple first power consumption prediction information of multiple single cores; if both the first warning information and the second warning information are warnings, then sequentially Power consumption control is carried out in the core, and resource interaction is carried out with the subsystem controller according to the power consumption control information. It is possible to control the power consumption in advance before the voltage abnormality occurs through the predictive method, and the power consumption control can be performed in advance before the abnormality occurs, and the abnormality of the chip can be effectively controlled. In a multi-core scenario, while performing power consumption control in the single-core local area, the resource interaction between the subsystem controller and the single-core local area can be performed more effectively to control the power consumption of the single-core local area and improve chip power integrity. .

Description

technical field [0001] Embodiments of the present invention relate to chip control technology, and in particular to an on-chip power consumption management method, electronic equipment and storage media. Background technique [0002] With the improvement of integrated circuit manufacturing technology, the computing power density of chips increases accordingly. With the increase of the computing power density of the chip, the power integrity requirements of the chip are getting higher and higher. [0003] At present, during the operation of the chip, there will be a large current change in the chip in a short period of time. For example, a current change of several hundreds of amperes occurs in a short time of nanosecond order. This will cause a large voltage drop (VoltageOvershoot) in the chip voltage. The voltage drop is likely to cause problems such as abnormal operation of the chip. [0004] How to effectively control chip abnormalities has become an urgent problem to...
