Abstract: This disclosure provides a data migration method and apparatus. The method includes: obtaining, by a first node from a second node, to-be-migrated data and a version number of the to-be-migrated data; obtaining from a third node, a version number of data that belongs to a same first service as the to-be-migrated data, wherein the data of the first service is distributively stored in the second node and the third node; and discarding the to-be-migrated data read from the second node when the first node determines that the version number of the to-be-migrated data obtained from the second node is different from a version number of data obtained from the third node.

Abstract: This application provides a chip, a dynamic vision sensor, and a method for outputting pixel information. The chip includes a pixel array and a processing circuit, and each pixel row in the pixel array includes at least two pixel groups. In the processing circuit, based on a change of a light intensity value of at least one pixel in a first pixel group, a first signal including row location information of the first pixel group in the pixel array is generated, and a second signal including column location information of a pixel row in which the first pixel group is located is generated. The first signal and the second signal are sent to a pixel output circuit, to enable the pixel output circuit to accurately output location information of the first pixel group whose light intensity value changes in the pixel array.

The optical-to-electrical conversion circuit may be configured to generate a first current based on incident light that is incident on the pixel. The composite measurement circuit is coupled to the optical-to-electrical conversion circuit. The pixel may have a first operating mode and a second operating mode. The composite measurement circuit may generate a first pulse signal based on the first current when the pixel operates in the first operating mode, where the first pulse signal represents the intensity information of the incident light. When the pixel operates in the second operating mode, the pixel receives a plurality of sampling signals, and generates a plurality of second pulse signals based on the first current and the plurality of sampling signals.
