Problems solved by technology

[0003] However, for chips on the dividing line between the two grades, i.e. knife-edge chips, the actual minimum working voltage of these knife-edge chips will be slightly lower than the minimum working voltage of the grade, or the maximum operating frequency of the blade-edge chips will be higher than the highest working frequency of the grade. Frequency, at this time, if the DVFS strategy corresponding to this level is still used to process the chip, voltage will be wasted

Abstract

The invention provides a chip voltage configuration method and a related device, and the method comprises the steps: firstly determining a target test item according to the characteristics of a targetchip, the target test item being used for testing the performance of the target chip, and the performance comprising a chip rate; then, determining M lowest working voltages of the target chip underN power frequencies according to the target test item, wherein M is a positive integer, and N is a positive integer larger than or equal to M; and finally, determining a target voltage configuration strategy according to the M lowest working voltages of the target chip. The most suitable voltage configuration strategy can be provided for each chip based on the lowest working voltage of each chip,the differentiation of the voltage regulation strategy of each chip is realized, and the power consumption is saved.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, and in particular, to a chip voltage configuration method and related devices. Background technique [0002] With the development of technology, the application of chips is becoming more and more extensive, and the requirements for chip quality are becoming more and more precise. The division of speed grades of chips can improve the work efficiency of chips. Divide chips with similar processing rates into the same level, and chips of the same level have the same minimum operating voltage, and adopt the same dynamic voltage and frequency scaling (DVFS) strategy for processing. [0003] However, for the chips on the dividing line between the two grades, that is, the blade edge chips, the actual minimum working voltage of these blade edge chips will be slightly lower than the minimum working voltage of the grade, or the maximum operating frequency of the blade edge chip will be...
