Abstract

The invention is suitable to be used in the field of data sampling and transmission, and provides a method and a device for self-adaptive sampling of multipath serial data, and an electronic device. The method comprises: in processes of normally receiving multipath serial data and sampling according to a work sampling clock, aimed at each path of serial data, respectively obtaining serial data asdetection data of each path of serial data; generating a plurality of detection data sampling clocks which sample aimed at the detection data of each path of serial data in sequence; according to theplurality of detection data sampling clocks, respectively sampling detection data of each path of serial data, the detection data being obtained at present, to obtain a sampling result; analyzing thesampling result to obtain an optimal detection data sampling clock of all paths of serial data; adjusting an operating sampling clock which samples aimed at all paths of serial data to a clock which is equal to the optimal detection data sampling clock; and sampling multipath serial data according to the adjusted operating sampling clock. In the method, normal work does not need to be interrupted,clock processing is simple, and the method and the device can accurately and reliably sample multipath serial data, to recovery data flow.

Description

technical field [0001] The invention belongs to the field of data sampling and transmission, in particular to a method, device and electronic equipment for self-adaptive sampling of multi-channel serial data. Background technique [0002] With the development of electronic information technology, various applications need to transmit a large amount of high-speed data. Serial data transmission technology has the advantages of fast transmission speed and strong anti-interference ability, and is widely used in many fields such as automotive electronics and security monitoring. [0003] In multi-channel serial data transmission, factors such as unequal length of PCB traces and different loads will affect the time for each data to reach the receiving end, and the relative phase of data and clock after each power-on is uncertain, and in normal operation Factors such as temperature during the process may even cause signal deviation, making it more difficult to recover data in real...
