[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] Embodiment 1: Embodiment 1 is an implementation scheme of the technical solution of the present application, such as Figure 1 As shown, this embodiment includes the following steps: S1. Get mouse events and the frequency of sending mouse data; The data transmission frequency of the connected mouse is read from the USB interface through the USB driver layer.
[0024] S2: If the data transmission frequency is greater than the graphics system response frequency, some events are deleted from the consecutive identical mouse events until the processing frequency required for the remaining mouse events is no greater than the graphics system response frequency. This includes the following sub-steps: (11) Put consecutive identical mouse events into the event queue in chronological order; (12) Every N mouse events, delete one event from the queue of consecutive identical mouse events; among them, an event that meets the following conditions is considered a consecutive identical mouse event:
[0025] in, Indicates the mouse button value, The subscript indicates the timing of obtaining the mouse key value.
[0026] (13) Determine whether the processing frequency required for the remaining mouse events is not greater than the response frequency of the graphics system. If so, the optimization is completed; otherwise, return to step (11).
[0027] Among them, the remaining mouse event processing frequency Specifically:
[0028] is the number of remaining mouse events; The sending time of consecutive identical mouse events; and must meet the following requirements: , For the remaining set of mouse events, A collection of consecutive identical mouse response events.
[0029] Among them, the graphics system response frequency is positively correlated with the CPU main frequency.
[0030] When the graphics system displays a mouse event, it obtains the movement increment of this mouse event, and then adds the movement increment to the coordinate information of the previous mouse event to obtain the coordinate information of this mouse event. Then, the coordinate information of this mouse event is updated based on the limitation of the screen range, and the graphics system displays this mouse event on the updated coordinate information.
[0031] Embodiment 2: Embodiment 2 provides another implementation method of the technical solution of the present application, such as Figure 2 As shown, the specific steps include: (1) The USB mouse hardware and embedded device are connected through the USB interface.
[0032] (2) The USB driver layer scans the mouse hardware information and obtains the mouse data transmission frequency.
[0033] (3) When the mouse is operated, such as moving, clicking, etc., mouse event data will be generated. The USB driver layer will report the mouse events and the mouse data transmission frequency to the graphics driver layer through the custom mouse data interface.
[0034] (4) The graphics driver layer determines whether to optimize based on the mouse data transmission frequency and mouse events and then sends them to the graphics system for display. Specifically: (41) Determine whether the data transmission frequency of the mouse is greater than the response frequency of the graphics system. If so, the connected mouse is deemed to be a high-speed mouse, and the process proceeds to step (42) to continue determining whether the display needs to be optimized. Otherwise, it indicates that the graphics system can process the received mouse events, and the process proceeds to step (44), where the graphics system directly displays the mouse events.
[0035] The maximum value of the response frequency of the graphics system can be set to the main core frequency of the CPU in the embedded device.
[0036] (42) Determine whether it is a continuous identical mouse event. If so, it means that the display can be optimized and will not affect the display effect of the graphics system. The mouse needs to be slowed down and the process goes to step (43). Otherwise, it is determined to be a critical mouse event and the display cannot be optimized. The process goes to step (44) and the graphics system directly displays the mouse event.
[0037] In this application, mouse events are represented by mouse key values, which are: left button 1; right button 2; scroll wheel 3; release button: 0; move: continuous same mouse key value.
[0038] 0-1-0 means clicking the left button; 0-0-0-0 means moving without pressing any button; 1-1-1-1-1 means moving with pressing the left button.
[0039] Consecutive identical mouse events appear as consecutive identical mouse button values.
[0040] (43) The specific speed reduction process is as follows: (431) Arrange consecutive identical mouse events in time sequence; (432) Every 10 mouse events, delete one event from the queue of consecutive identical mouse events; (433) Determine whether the processing frequency required for the remaining mouse events is not greater than the response frequency of the graphics system. If so, the optimization is completed and the process goes to step (44); otherwise, the process returns to step (431).
[0041] In this step, it can also be determined whether the average time interval between the remaining mouse events is not less than the minimum response time of the graphics system; if so, the optimization is completed and the process proceeds to step (44); otherwise, the process returns to step (431).
[0042] (44) The graphics driver layer sends each mouse event to the graphics system for display.
[0043] The graphics driver layer obtains the movement increment of this mouse event, and then adds the movement increment to the coordinate information of the previous mouse event to obtain the coordinate information of this mouse event, and then updates the coordinate information of this mouse event based on the screen range limit. Finally, the graphics system displays this mouse event on the updated coordinate information.
