Chip frequency modulation method and device of computing device, computing board, computing device and storage medium

Abstract

The invention provides a chip frequency modulation method and device, a computing board, a computing device and a storage medium. The chip frequency modulation method comprises the following steps: arranging a plurality of working frequency points for the computing chip of the computing device, and operating a plurality of cores in the computing chip on each working frequency point; analyzing whether the calculation accuracy of the kernel at the current operating frequency point reaches a predetermined first accuracy threshold value and / or a second accuracy threshold value within a predetermined adjustment period; if the calculation accuracy of the kernel reaches the first accuracy threshold, adjusting the current operating frequency point of the kernel up; and / or lowering the current operating frequency of the core if the calculation accuracy of the core does not reach the second accuracy threshold. Therefore, the frequency corresponding to each core can be automatically adjusted according to the actual calculation performance of each core in the calculation chip of the calculation device, thereby maximizing the calculation performance of the core and further improving the calculation performance of the calculation chip and the whole calculation device.

Description

technical field [0001] The present invention relates to the technical field of chip frequency modulation of computing equipment, and in particular to a chip frequency modulation method and device of computing equipment, a computing power board, computing equipment and a storage medium. Background technique [0002] Computing devices used for massive data computing usually integrate a large number of computing chips. Due to the limitation of the manufacturing process of computing chips, the working performance, computing power and frequency of different computing chips are not the same; at the same time, a single computing chip is usually composed of multiple The actual working performance of each core is also different due to differences in process deviation and voltage drop at different positions in the computing chip. In view of the differences in the working performance of different computing chips and their cores, how to dynamically adjust the actual frequency required b...

Problems solved by technology

It can be seen that CN201611169618.6 discloses that the regulator can adjust the frequency of the chip, but it only adjusts the operating frequency of the chip according to whether the power supply unit is normally sending and receiving data, voltage state, temperature state, frequency state and other working states. Frequency adjustment The mechanism lacks accuracy and cannot give full play to the computing performance of the chip

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
