Example Embodiment

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

[0024] In this embodiment, a data transmission method is provided, figure 1 Is a flowchart of a data transmission method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0025] Step S102, buffer the data transmitted to the universal serial bus (USB) physical controller;

[0026] Step S104: When the cached data meets a preset condition, the above-mentioned cached data is transmitted to the USB physical controller.

[0027] In this embodiment, through the above steps, the data transmitted to the USB physical controller is first cached. When the cached data meets the preset conditions, the cached data is transferred to the USB

Abstract

The invention discloses a data transmission method and device. The method comprises the steps as follows: caching data transmitted to a USB physical controller; transmitting the cached data to the USB physical controller under the condition that the cached data meet preset conditions. With the adoption of the data transmission method and device, the problem that the USB physical controller is lower in usage rate in related technologies is solved, and the utilization rate of the USB physical controller is increased; in addition, the data volume processed by the USB physical controller at a time is increased, so that the utilization rate of a master controller is also increased, and the occupation rate of the USB physical controller to the master controller is reduced.
