Detailed Description
In the present disclosure, unless otherwise specified, the use of the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, the timing relationship, or the importance relationship of the elements, and such terms are used only to distinguish one element from another. In some examples, a first element and a second element may refer to the same instance of the element, and in some cases, based on the context, they may also refer to different instances.
The terminology used in the description of the various examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the elements may be one or more. As used herein, the term "plurality" means two or more, and the term "based on" should be interpreted as "based, at least in part, on". Further, the terms "and/or" and at least one of "… …" encompass any and all possible combinations of the listed items.
In the related art, a graphics processing chip may include a graphics rendering unit for rendering graphics data to be rendered and a display unit for displaying the rendered graphics data. As described above, the graphics processing chip can be applied to electronic devices such as a personal computer, a tablet computer, a smart phone, etc. to perform graphics-related operations (e.g., rendering and displaying graphics data). In application scenarios such as personal computers, tablet computers, smart phones, etc., the graphics rendering unit and the display unit of the graphics processing chip are typically integrated on the same graphics processing chip.
With the development of technology, a need for image or graphic display on wearable electronic devices has arisen. Therefore, a graphics processing chip capable of being applied to a wearable electronic device is needed. Due to technical limitations, the graphics rendering unit and the display unit of the graphics processing chip applied to the wearable electronic device are not usually integrated on the same graphics processing chip; instead, the display unit is provided on the wearable device for graphical display and the graphics rendering unit is provided on a computer communicatively connected to the wearable device for graphical rendering. Therefore, the graphic data rendered by the graphic rendering unit can be transmitted to the display unit arranged on the wearable device to jointly complete the tasks of graphic rendering and display. The reason for this non-integrated arrangement is, on the one hand, that the wearable device itself has limited design space, which is not favorable for arranging the graphics rendering unit and possibly the matching components of the graphics rendering unit thereon; on the other hand, even if the graphic rendering unit and the related matching components possibly existing on the wearable device can be arranged on the wearable device, the result is that the total weight of the wearable device is greatly increased, and the wearing experience of the user of the wearable device is seriously affected. For example, with the development of Virtual Reality (VR) technology, more and more graphics processing chips are used in VR scenes. The graphics rendering unit in the computer for VR undertakes the graphics rendering task, while the display unit undertakes the task of displaying VR image content, usually in the VR headset, with a connection over a local area network.
It can be seen that, in the related art, the configurations of the graphics processing chips used in the common scene and the wearable device scene are inconsistent and cannot be used interchangeably. Therefore, manufacturers of the graphics processing chips have to design different graphics processing chips for two different scenes, which greatly increases the cost in the links of research and development, debugging, production, manufacturing, after-sales service, and the like.
In view of this, the present disclosure proposes a chip for graphics processing, which is compatible with a scenario of an electronic device such as a general computer and a scenario of a wearable electronic device (e.g., a wearable VR device). This reduces the development and manufacturing costs of the chip applied to the above two scenarios.
Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a block diagram illustrating a structure of a chip 100 for graphics processing according to an exemplary embodiment. As shown in fig. 1, a chip 100 for graphics processing includes:
a graphics rendering unit 110 configured to render graphics data to be rendered;
a data selector 120 configured to have a first operation mode and a second operation mode and to be switchable between the first operation mode and the second operation mode;
the local display unit 130, the data selector 120 is further configured to connect the local display unit 130 and the graphics rendering unit 110 in the first operation mode, and the local display unit 130 is configured to acquire the graphics data rendered by the graphics rendering unit 110 through the data selector 120 for displaying; and
the virtual display unit 140, the data selector 120 is further configured to connect the virtual display unit 140 and the graphics rendering unit 110 in the second operation mode, and the virtual display unit 140 is configured to obtain the graphics data rendered by the graphics rendering unit 110 through the data selector 120 and send the graphics data to an external display unit communicatively connected to the chip for display.
By providing the virtual display unit 140 capable of communicative connection with the external display unit and the data selector 120 capable of switching between the first operation mode and the second operation mode in the chip 100, the chip 100 can be applied to a scene of an electronic device such as a general computer when the local display unit 130 and the graphic rendering unit 110 are connected by the data selector 120 in the first operation mode; when the data selector 120 connects the virtual display unit 140 and the graphics rendering unit 110 in the second operation mode, the chip 100 can be applied to a scene of a wearable electronic device (e.g., a wearable VR device). Therefore, the chip 100 can be compatible with scenes of electronic devices such as a common computer and scenes of wearable electronic devices (such as wearable VR devices), and only a data selector is needed to be added to connect the graphics rendering unit and the display unit, and a virtual display unit for forwarding data between the graphics rendering unit and an external display unit is arranged, so that the electronic device is simple to connect and transform, and is convenient to implement.
For example, the chip 100 may be installed in a motherboard of a computer, and the local display unit 130 of the chip 100 is connected to a display of the computer, so that the chip 100 may trigger the display of the computer to perform graphic display. Furthermore, the chip 100 disposed in the computer may also be communicatively connected to a wearable electronic device (e.g., a wearable VR device), for example, via the virtual display unit 140 of the chip 100 to an external display unit on the wearable electronic device, so that the chip 100 may also trigger a display on the wearable electronic device (e.g., a display on a VR headset) to perform a graphic display.
The data selector may be a multiplexer or a multiplexer switch. The user can switch the data selector between the first working mode and the second working mode by adjusting the configuration parameters of the register of the data selector according to the scene requirements. That is, the data selector may be connected to the local display unit 130 or to the virtual display unit 140 by parameter adjustment of a register of the data selector. In some examples, the chip 100 may automatically switch the first operating mode and the second operating mode according to different hardware (e.g., a display) communicatively coupled to the chip 100.
It should be understood that the external display unit may be a remote display unit. The external display unit may be a display unit in a VR headset, which may be connected within the same local area network as the virtual display unit 140. Thereby, the external display unit can wirelessly transmit with the virtual display unit 140.
According to some embodiments, the virtual display unit 140 may be configured to acquire, through the data selector 120, the graphic data rendered by the graphic rendering unit 110 and transmit the graphic data rendered by the graphic rendering unit 110 to the external display unit for display, in response to receiving a data request instruction transmitted by the external display unit.
The data request instruction may be an instruction to request rendered graphics data from the chip 100. In some examples, the graphics rendering unit 110 may temporarily store the rendered graphics data in a buffer or a corresponding memory, and when the virtual display unit 140 receives a data request instruction sent by an external display unit (e.g., an external display unit disposed in a VR headset), the rendered graphics data is provided to the external display unit for display through the data selector 120.
According to some embodiments, the data selector 120 may be configured to receive the first display response information from the local display unit 130, and the graphics rendering unit 110 may be configured to perform rendering of subsequent graphics data based on the first display response information, the first display response information being for instructing the local display unit 130 to complete display of the acquired graphics data.
Thus, by receiving the first display response message from the local display unit 130 through the data selector 120, the graphics rendering unit 110 can respond in time that the graphics data sent to the local display unit 130 have been displayed by the local display unit 130, so that the rendering of the subsequent graphics data (e.g., next frame of graphics data) can be performed in time, and the video based on the multi-frame of graphics data displayed by the local display unit 130 is not jammed.
According to some embodiments, the virtual display unit 140 may be configured to receive second display response information from the external display unit, and the graphics rendering unit 110 may be configured to perform rendering of subsequent graphics data based on the second display response information for instructing the external display unit to complete display of the acquired graphics data.
Thus, by receiving the second display response message from the external display unit through the data selector 120, the graphics rendering unit 110 can respond in time that the graphics data sent to the external display unit has been displayed by the external display unit, so that the rendering of the subsequent graphics data (e.g., next frame of graphics data) can be performed in time, and the video based on the multiple frames of graphics data displayed by the external display unit is not jammed.
Fig. 2 is a block diagram illustrating a structure of a chip 200 for graphics processing according to an exemplary embodiment. The chip 200 includes a graphics rendering unit 210, a data selector 220, a local display unit 230, and a virtual display unit 240, which are similar to the corresponding components of the chip 100 described with respect to fig. 1, and are not described again here.
As shown in fig. 2, according to some embodiments, the first display response information may be interrupt information, and the chip 200 may include a first interrupt connection line 251 connecting the data selector 220 and the local display unit 230, and in the first operation mode of the data selector 120, the data selector 120 receives the first display response information from the local display unit 230 through the first interrupt connection line 251.
It is understood that the interrupt information may be a vertical interrupt signal, and the vertical interrupt signal may be used to indicate that the local display unit 230 has completed drawing the screen graphic once.
With continued reference to fig. 2, according to some embodiments, the second display response information may be interrupt information, and the chip 200 may include a second interrupt connection line 252 connecting the data selector 220 and the virtual display unit 240, and in the second operation mode of the data selector 220, the data selector 220 receives the second display response information from the virtual display unit 240 through the second interrupt connection line 252.
It is to be understood that the interrupt information may be a vertical interrupt signal, and the vertical interrupt signal may be used to indicate that the external display unit has completed drawing the screen graphic once.
It can be seen that both local display unit 130 and virtual display unit 140 may be connected to data selector 120 via respective interrupt connection lines. Therefore, in a scene of an electronic device such as a general computer and a scene of a wearable electronic device (e.g., a wearable VR device), the graphics rendering unit 210 of the chip 200 can receive corresponding interrupt signals.
With continued reference to fig. 2, according to some embodiments, the chip 200 may further include a first register connection line 261 connecting the data selector 220 and the local display unit 230, and a second register connection line 262 connecting the data selector 220 and the virtual display unit 240. And the chip 200 is configured to transmit the register configuration instruction to the local display unit 230 through the first register connection line 261 via the data selector 220 in the first operation mode of the data selector 220. And the chip 200 is further configured to transmit a register configuration instruction to the virtual display unit 240 through the second register connection line 262 via the data selector 220 in the second operation mode of the data selector 220, and the virtual display unit 240 is configured to transmit the register configuration instruction to the external display unit.
Accordingly, the registers of the local display unit 230 and the registers of the external display unit connected to the virtual display unit 240 can be initialized and configured via the data selector 220, thereby ensuring that the local display unit 230 and the external display unit can smoothly display the acquired graphic data.
According to another aspect of the present disclosure, a wearable electronic device is also provided. Fig. 3 is a block diagram illustrating a wearable electronic device 300 according to an example embodiment. The wearable electronic device 300 comprises a display unit 310 communicatively connected to the chip 100 or the chip 200 according to the above, the display unit 310 being configured to: receiving rendered graphics data from the virtual display unit (140 or 240) of chip 100 in FIG. 1 or 200 in FIG. 2; and displaying an image corresponding to the rendered graphics data. By receiving the rendered graphical data from the virtual display unit 140 of the chip 100 or from the virtual display unit 240 of the chip 200, the wearable electronic device 300 may display a corresponding image on its display. The wearable electronic device 300 may be a wearable electronic device having a display function, such as VR glasses and AR glasses.
According to some embodiments, the display unit 310 may be further configured to send a data request instruction to the virtual display unit (140 or 240) of the chip 100 or 200, so that the virtual display unit acquires the rendered graphic data through the data selector (120 or 220) and sends the rendered graphic data to the display unit 310. Thus, the display unit 310 can obtain the corresponding graphic data from the chip 100 or 200 according to its requirement.
According to some embodiments, the display unit 310 may be configured to transmit a data request instruction to the virtual display unit (140 or 240) at a preset cycle. In some examples, after display unit 310 sends the data request instruction to virtual display unit 140 or 240, the corresponding rendered graphics data may not be received (e.g., a frame of graphics data may not have been rendered by the graphics rendering unit of chip 100 or 200). Therefore, by causing the display unit 310 to transmit a data request instruction to the virtual display unit 140 or 240 at a preset cycle, it can be ensured that the display unit 310 can receive graphic data corresponding to the data request instruction, thereby smoothly completing image display.
According to another aspect of the present disclosure, there is also provided a processing method 400 for graphics data of a chip. The chip includes a graphics rendering unit, a local display unit, a virtual display unit, and a data selector having a first operating mode and a second operating mode and being switchable between the first operating mode and the second operating mode. For example, the chip may be chip 100 or chip 200 described above.
FIG. 4 is a flowchart illustrating a method 400 of processing graphics data for a chip, according to an example embodiment.
As shown in fig. 4, the method 400 includes:
step S410, rendering the graphic data to be rendered by using a graphic rendering unit;
step S420, responding to the data selector in the first working mode, the local display unit obtains the graphic data rendered by the graphic rendering unit through the data selector for displaying; and
and step S430, responding to the second working mode of the data selector, the virtual display unit acquires the graphic data rendered by the graphic rendering unit through the data selector and sends the graphic data to an external display unit in communication connection with the chip for displaying.
The data selector can switch between the first working mode and the second working mode. When the data selector connects the local display unit and the graphics rendering unit in the first operating mode, the display of graphics data can be performed in a scene of an electronic device such as a general computer; when the data selector is connected with the virtual display unit and the graphic rendering unit in the second working mode, graphic data can be displayed in a scene of wearable electronic equipment (such as wearable VR equipment), and only the data selector needs to be added to connect the graphic rendering unit and the display unit and set the virtual display unit for forwarding data between the graphic rendering unit and the external display unit.
According to some embodiments, step S430 may comprise: the virtual display unit responds to a received data request instruction sent by the external display unit, obtains the graphic data rendered by the graphic rendering unit through the data selector, and sends the graphic data rendered by the graphic rendering unit to the external display unit for displaying.
The data request instruction sent by the external display unit may be a data request instruction sent from a display unit on a wearable electronic device (e.g., a wearable VR device). The data request instruction may be an instruction to request rendering of graphics data from the chip. In some examples, the graphics rendering unit may temporarily store its rendered graphics data in a buffer or a corresponding memory, and when the virtual display unit receives a data request instruction sent by an external display unit (e.g., an external display unit disposed in a VR headset), the rendered graphics data is provided to the external display unit for display by the data selector.
According to some embodiments, the method 400 may further comprise:
the data selector receives first display response information from the local display unit; and
the graphics rendering unit performs rendering of subsequent graphics data based on first display response information indicating that the local display unit completes display of the acquired graphics data.
Therefore, the data selector receives the first display response information from the local display unit, and the graphics rendering unit can respond that the graphics data sent to the local display unit are displayed by the local display unit in time, so that the subsequent graphics data (such as next frame of graphics data) can be rendered in time, and the video based on the multi-frame graphics data displayed by the local display unit is free of blockage.
According to some embodiments, the first display response information may be interrupt information, and the chip may include a first interrupt connection line connecting the data selector and the local display unit. The method 400 may further include:
in a first operating mode of the data selector, the data selector receives first display response information from the local display unit through the first interrupt connection line.
It will be appreciated that the interrupt information may be a vertical interrupt signal, which may be used to indicate that the local display unit has completed drawing the screen graphic once.
According to some embodiments, the method 400 may further comprise:
the virtual display unit receives second display response information from the external display unit; and
the graphics rendering unit performs rendering of subsequent graphics data based on second display response information for instructing the external display unit to complete display of the acquired graphics data.
Therefore, the data selector receives the second display response information from the external display unit, the graphics rendering unit can timely respond that the graphics data sent to the external display unit are displayed by the external display unit, and then the subsequent graphics data (such as next frame of graphics data) can be rendered timely, so that the video based on the multi-frame graphics data displayed by the external display unit is free of pause.
According to some embodiments, the second display response information may be interrupt information, and the chip may include a second interrupt connection line connecting the data selector and the virtual display unit. The method 400 may further include:
and in a second working mode of the data selector, the data selector receives second display response information from the virtual display unit through the second interrupt connecting line.
It is to be understood that the interrupt information may be a vertical interrupt signal, and the vertical interrupt signal may be used to indicate that the external display unit has completed drawing the screen graphic once.
According to some embodiments, the chip further comprises a first register connection line connecting the data selector and the local display unit and a second register connection line connecting the data selector and the virtual display unit. The method 400 may further include:
under a second working mode of the data selector, transmitting a register configuration instruction to the virtual display unit through the data selector by a second register connecting line; and
the register configuration instruction is sent to an external display unit using a virtual display unit.
Accordingly, the register of the local display unit and the register of the external display unit connected to the virtual display unit can be initialized and configured through the data selector, and the local display unit and the external display unit can display the acquired graphic data smoothly.
In some examples, the register configuration instructions may be transmitted to an external display unit (e.g., VR glasses) through the data selector and the virtual display unit prior to the graphics rendering unit rendering the graphics data to be rendered.
To better illustrate how graphics data processing may be performed using a chip according to an embodiment of the disclosure, further description will be provided below in conjunction with fig. 5. Fig. 5 is a diagram illustrating a scenario in which a chip and a wearable electronic device according to an exemplary embodiment are applied for graphic data processing and display.
As shown in fig. 5, the chip 500 may be the same as the chip 100 or the chip 200 described above, and the chip 500 includes a graphic rendering unit 510, a data selector 520 having a first operation mode and a second operation mode, a local display unit 530, and a virtual display unit 540. In addition, the data selector 520 is connected to the local display unit 530 and the virtual display unit 540 via the interrupt connection lines 551 and 552, respectively; and the data selector 520 is connected to the local display unit 530 and the virtual display unit 540 through register connection lines 561 and 562, respectively. The wearable electronic device 590 may be the same as the wearable electronic device 300 described above.
The data selector 520 of the chip 500 may be set to a first operation mode (i.e., the data selector 520 is connected to the local display unit 530), and thus, the chip 500 may be used in a scene of an electronic device such as a general computer. In this context, the following description will not be repeated.
Furthermore, the data selector 520 of the chip 500 may also be set to a second operation mode (i.e. connecting the data selector 520 with the virtual display unit 540), whereby the chip 500 may be used in a scenario for a wearable electronic device (e.g. a VR device). In this scenario, the virtual display unit 540 and the external display unit 591 (the display unit of the wearable electronic device 590) may communicate over a wireless network connection (as shown by the dashed arrow in fig. 5).
In a scenario for a wearable electronic device (e.g., a VR device), first, register configuration instructions may be sent to the virtual display unit 540 via the data selector 520 through a register connection line between the data selector 520 and the virtual display unit 540; after receiving the register configuration instruction, the virtual display unit 540 may send the register configuration instruction to an external display unit 591 on the wearable electronic device 590 (e.g., VR glasses) through the wireless local area network; after receiving the register configuration instruction, the external display unit 591 may perform initial configuration on its own register, so as to perform required parameter configuration for subsequent graphic display.
Graphics rendering unit 510 of chip 500 may process graphics rendering tasks submitted by a user, i.e., graphics rendering unit 510 may render each frame of graphics data separately. The graphics rendering unit 510 may store a frame of rendered graphics data in the memory of the chip 500 after completing rendering of the frame of graphics data.
An external display unit 591 (for convenience of explanation, the external display unit 591 is a display unit of the wearable electronic device 590, and is unified with the terms in the above description for convenience of understanding) in the wearable electronic device 590 may send a data request instruction to the virtual display unit 540 of the chip 500 through the wireless network according to a preset period. After receiving the data request instruction from the external display unit 591, the virtual display unit 540 may read the graphics data rendered by the graphics rendering unit 510 from the memory of the chip 500, and send the rendered graphics data to the external display unit 591 on the wearable electronic device 590 again through the wireless network. The external Display unit 591 may process the received graphics data (e.g., convert it into a Display interface signal, such as a Display Port signal, suitable for Display), and Display the corresponding image on the Display screen of the wearable electronic device 590.
When the external display unit 591 completes displaying one frame of graphic data, an interrupt signal (e.g., Vsync interrupt signal) may be generated and transmitted to the virtual display unit 540 of the chip 500 through a wireless network. Based on the interrupt signal received from the external display unit 591, the graphics rendering unit 510 of the chip 500 may render the next frame of graphics data and store the rendered next frame of graphics data in the memory, thereby waiting for the virtual display unit 540 to read the next frame of graphics data.
Thus, the chip 500 completes the task of transmitting and displaying the graphic data together with the wearable electronic device in the scene of the wearable electronic device (e.g., VR device). It can be seen that the chip 500 is compatible with the scenarios of electronic devices such as a general computer and the scenarios of wearable electronic devices (e.g., wearable VR devices).
