Abstract

The invention discloses dynamic processor adjustment method and device and a processor chip. Multi-direction processor information can be combined for dynamic adjustment; maximum working frequency isobtained through current working status data of a processor; An expectation task amount is combined to obtain a task amount evaluation parameter, and then weighting task amount parameters are obtained; optimal working frequency is obtained through comparing the task amount evaluation parameter with the weighting task amount parameters; and the optimal working frequency is written into the processor to realize frequency adjustment. Various sensors are utilized to collect different sensor information, a current working condition of the processor is acquired, dynamic workload status of the processor is combined to comprehensively evaluate current working status of the processor, composite status reflecting multi-aspect information of the processor is utilized to dynamically adjust working frequency and voltage of the processor, and thus performance and power consumption of the processor are better balanced.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a processor dynamic adjustment method, device and processor chip. Background technique [0002] With the continuous improvement of the level of integrated circuit technology, the scale of integrated circuits is also rapidly increasing at a rate of doubling every one and a half years under the guidance of Moore's Law. From single-function chips to system-on-chips, and toward the direction of on-chip networked chips. Higher performance is the constant goal of high-end integrated circuit development. For a chip with a certain architecture, increasing the operating frequency can greatly improve the performance of the chip. However, the operating frequency of the chip is affected by many factors. For commercial products, the final maximum operating frequency is often determined by the short board in the batch of chips, that is, it is uniformly determined by the frequency of the l...
