Abstract

The invention provides a data processing calibration method and device, a chip, equipment, a medium and a product. Related embodiments can be applied to various scenes such as cloud technology, artificial intelligence and intelligent transportation. The calibration method for data processing comprises the following steps: performing measurement processing based on a clock measurement unit in a data processing process to obtain a plurality of measurement clock periods; the measurement clock period is used for representing a plurality of clock measurement units; according to the number of the clock measurement units respectively represented by the plurality of measurement clock periods, determining whether clock drift exists among the plurality of measurement clock periods; when the clock drift exists among the plurality of measurement clock periods, determining a delay parameter for the clock drift according to at least part of the measurement clock periods with the latest measurement time in the plurality of measurement clock periods; and performing clock calibration processing in the data processing process according to the delay parameter. Through the data processing method and device, the accuracy of data processing can be improved, and the problem of data processing errors caused by clock drift is effectively avoided.

Description

technical field [0001] The present application relates to electronic technology, and in particular to a data processing calibration method, device, chip, equipment, medium, and product. Background technique [0002] With the rapid development of electronic technology, the computing power of various electronic devices is also increasing rapidly. Taking the High Bandwidth Memory (HBM) chip as an example, the data transmission speed can reach 2Gbps under the 16nm process, 2.4Gbps under the 7nm process, and 3.2Gbps under the 5nm process. Even 3.6Gbps. [0003] Efficient data transmission speed also means higher operating frequency. Taking HBM PHY as an example, its comprehensive operating frequency can reach up to about 1.8GHz. At such a high operating frequency, if the working environment of the electronic device changes, even if the change is small, it will cause clock drift inside the electronic device, and the data eye diagram will become pessimistic, which will greatly in...
