Embodiment 1

[0050] Reference figure 1 , Shows a step flow chart of an interface access method in the first embodiment of the present invention. The method is applied to a display device. The display device includes an on-screen menu board (hereinafter referred to as an OSD board) and a field programmable gate array board. (Hereinafter referred to as FPGA board), OSD board and FPGA board are connected through an interface. The following specifically provides a display device including an OSD board and an FPGA board connected by an interface, that is, an 8K monitor, refer to figure 2 , Shows a schematic diagram of the basic structure of an 8K monitor in Embodiment 1 of the present invention. The 8K monitor is currently an essential display device for realizing ultra-high-definition video playback and live broadcasting.

[0051] Reference figure 2 The 8K monitor may include an OSD board 10 and an FPGA board 20 that are interfaced, and an 8K display 30, where the 8K display 30 and the FPGA boar...

Embodiment 2

[0114] Reference Figure 8 , Shows a structural block diagram of a display device of the second embodiment of the present invention. The display device includes a screen menu board 100 and a field programmable gate array board 200. The screen menu board 100 and the field programmable The door array board 200 is connected through interface 01;

[0115] The on-screen menu board 100 is configured to periodically access the interface according to a preset access mode in the case of receiving an instruction to view the volume interface of the audio input device, and through the interface, from the field programmable door The array board 200 reads audio input device volume data and video channel access state data in an interleaved manner; the preset access method includes an interface to the audio input device volume data for the first preset number of executions in each cycle After the access operation, perform a second preset number of interface access operations to the video channe...

Embodiment 3

[0121] The embodiment of the present invention also discloses an electronic device including the above-mentioned display device.

[0122] In the embodiment of the present invention, the on-screen menu board of the display device may periodically access the interface according to the following preset access mode when receiving a user-triggered viewing instruction of the audio input device volume interface. In each cycle, after the first preset number of interface access operations to the audio input device volume data are performed, the second preset number of interface access operations to the video channel access state data is performed. After that, the on-screen menu board can read audio input device volume data and video channel access status data from the field programmable gate array board through the interface with the field programmable gate array board of the display device. Realize the serial access of the interface, avoid interface access conflicts, and ensure the real-...

Abstract

The invention provides an interface access method, a display device and electronic equipment, and relates to the technical field of display. The method comprises the following steps: when a screen menu board card receives a viewing instruction of a microphone volume interface, periodically accessing the interface according to a preset access mode, the preset access mode comprising, in each period,after each execution of an interface access operation on the microphone volume data for a first preset number of times, executing an interface access operation on the video channel access state datafor a second preset number of times; and enabling the screen menu board card to read microphone volume data and video channel access state data from the field programmable gate array board card in a staggered manner through an interface. Thus, serial access of the interface between the screen menu board card and the field programmable gate array board card can be realized, interface access conflicts are avoided, and the real-time performance of microphone volume data and video channel access state data is ensured.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an interface access method, display device and electronic equipment. Background technique [0002] In display devices such as high-resolution monitors, in addition to the display screen, there are usually two interfaces that can be displayed, one is OSD (on screen display, on-screen menu) for displaying setting information such as contrast, and the other is A pop-up box used to display related attributes such as playback volume and access signal. Among them, the OSD interface and the pop-up box are displayed and managed by the OSD application. [0003] At present, all the setting operations used for display in OSD applications are realized by the OSD board sending commands to the FPGA (Field-Programmable Gate Array) board through the interface. The interface is used as a shared device. Only one read or write operation is allowed at a time. In current applications, many thread...
