Description

Graphics processor, system, apparatus, device, and method
Technical Field
The present disclosure relates to the field of image rendering technologies, and in particular, to a GPU (Graphics Processing Unit, graphics processor), a system, an electronic device, an electronic apparatus, and a graphics processing method.
Background
In the texture mapping process of an image, in order to increase the rendering speed and reduce texture jaggies, the texture mapping is processed into a file composed of a series of pre-computed and optimized pictures. The set of files includes multi-level precision texture maps, each level of texture maps having half the precision (i.e., resolution) of its previous level of texture map. The texture map thus processed is referred to as a multi-level fade (Mipmap) texture. After the Mipmap texture is used, texture mapping with different precision can be selected according to the distance between the camera and the camera when mapping.
Because the corresponding texture maps of multiple accuracies are loaded according to the camera examples, the use of Mipmap textures necessarily takes up more memory.
To reduce GPU memory occupied by Mipmap textures, it is conventional practice for software to obtain miplets (Mipmap levels) that the hardware computes at the time of texture sampling. Since some areas in a frame of image are close to the camera and some areas are far from the camera, the Miplevel obtained after hardware calculation is usually in an interval range, that is, software obtains a minlevel (minimum level) and a maxlevel (maximum level), and the MipMap texture between the minlevel and the maxlevel is loaded into the video memory.
Although the conventional method reduces the range of the loaded MipMap texture, the conventional method still causes the waste of the video memory space to a certain extent.

Detailed Description
Before describing embodiments of the present disclosure, it should be noted that:
some embodiments of the disclosure are described as process flows, in which the various operational steps of the flows may be numbered sequentially, but may be performed in parallel, concurrently, or simultaneously.
The terms "first," "second," and the like may be used in embodiments of the present disclosure to describe various features, but these features should not be limited by these terms. These terms are only used to distinguish one feature from another.
The term "and/or," "and/or" may be used in embodiments of the present disclosure to include any and all combinations of one or more of the associated features listed.
It will be understood that when two elements are described in a connected or communicating relationship, unless a direct connection or direct communication between the two elements is explicitly stated, connection or communication between the two elements may be understood as direct connection or communication, as well as indirect connection or communication via intermediate elements.
In order to make the technical solutions and advantages of the embodiments of the present disclosure more apparent, the following detailed description of exemplary embodiments of the present disclosure is provided in conjunction with the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments of which are exhaustive. It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.
In order to further reduce the memory space occupied by the MipMap texture, the present disclosure provides a GPU that loads the MipMap texture based on MipMap feedback blocking. The Mipmap texture is partitioned (i.e., chunked) into regions, and the Mipmap texture corresponding to Miplevel is loaded in chunks by counting the Mipmap feedback (including Miplevel) within each region. In conventional schemes, even a small portion of the Mipmap texture of a Miplevel has to be loaded into memory in its entirety. Compared with the traditional scheme, the embodiment of the disclosure can load partial textures of the hierarchy instead of complete textures according to the mipevel, so that the video memory space is saved. In addition, due to the reduction of the amount of Mipmap texture data, the communication delay and bandwidth between the CPU (Central Processing Unit ) and the GPU are also effectively reduced.
The GPU refers to a processor with a computing function and realized by hardware, and comprises a computing unit, a cache and other components, which can be a GPGPU (general-purpose graphics processing unit) or a GPU.
The graphics processor provided by the embodiments of the present disclosure is applicable to tile-based rendering architectures, such as TBR (Tile Based Render, tile-based rendering), TBDR (Tile Based Deferred Rendering, tile-based deferred rendering), etc., as well as IMR (Immediate Mode Rendering ) architectures.
One embodiment of the present disclosure provides a graphics processor that includes at least a multi-level taper level (i.e., miplevel) determination module and a texture tile determination module.
Wherein the multi-level taper level hierarchy determination module is configured to: and determining the corresponding Miplevel of each texture coordinate according to the input pixel coordinates and the texture coordinates.
Embodiments of the present disclosure are not limited to a particular implementation of the multi-level taper level determination module to determine mipevel, which may be implemented using existing implementations or existing implementation principles.
Wherein the texture tile determination module is configured to: and determining the Mipmap texture area to which each texture coordinate belongs.
In the disclosed embodiment, the Mipmap texture is divided into a plurality of regions. By way of example and not limitation, as shown in fig. 1, the Mipmap texture includes four levels of Miplevel1, miplevel2, miplevel3, and Miplevel4, where the Miplevel1 texture map is the original resolution texture map. The Mipmap texture is divided into three regions, each of which is divided in the same manner. The three Mipmap texture areas are Mipmap texture area 1, mipmap texture area 2 and Mipmap texture area 3, respectively. The texture coordinate range of the Mipmap texture region 1 is (U0 min, V0 min), (U0 max, V0 max), the texture coordinate range of the Mipmap texture region 2 is (U1 min, V1 min), (U1 max, V1 max), and the texture coordinate range of the Mipmap texture region 3 is (U2 min, V2 min), (U2 max, V2 max). Taking Miplevel2 as an example, in the texture map of Miplevel2, the Mipmap texture region is divided in the same manner as in Mipmap level1, but since the resolution is halved, the region size is halved.
In the embodiment of the disclosure, the determining of the Miplevel corresponding to each texture coordinate generates Miplevel information, where the Miplevel information indicates the Miplevel corresponding to each texture coordinate. The mipevel information may be generated and output by the multi-stage progressively farther hierarchy determination module, or by other hardware modules in the GPU, as the embodiments of the present disclosure are not limited in this regard.
In the embodiment of the disclosure, determining the Mipmap texture area to which each texture coordinate belongs generates Mipmap texture area information, where the Mipmap texture area information indicates the Mipmap texture area to which each texture coordinate belongs. The Mipmap texture region information may be generated and output by the texture partition determination module, or may be generated and output by other hardware modules in the GPU, which is not limited by the embodiments of the present disclosure.
In the disclosed embodiments, the functions of the multi-level taper level determination module and the texture partition determination module may be implemented by existing hardware, such as with an existing ALU. The functions of the multi-level progressively farther hierarchy determination module and the texture partition determination module may also be implemented by developing new hardware.
In the embodiment of the disclosure, texture loading software obtains Miplevel information and Mipmap texture region information, determines Miplevel corresponding to each Mipmap texture region according to the Miplevel information and the Mipmap texture region information, and loads a multi-level gradually-distant texture region of the corresponding Mipmap.
The texture loading software can determine the Mipmap texture region to which each texture coordinate belongs according to the Mipmap texture region, that is, can determine the texture coordinates respectively covered by each Mipmap texture region. The texture loading software can determine the Miplevel corresponding to each texture coordinate according to the Miplevel information, that is, for each Mipmap texture region, the Miplevel corresponding to the texture coordinate covered by the Mipmap texture region can be determined.
In some embodiments, the Mipmap texture region covers the Miplevel corresponding to the texture coordinates, i.e., the Mipmap texture region. Assuming that the texture coordinates covered by a Mipmap texture region correspond to three Miplevel, the Mipmap texture region corresponds to three Miplevel.
In some embodiments, the Mipmap texture region covers the maximum and minimum levels of texture coordinates and the Miplevel between them, i.e., the Mipmap texture region corresponds to Miplevel. Assuming that the texture coordinates covered by a Mipmap texture region correspond to three Miplevel, the Mipmap texture region corresponds to the Miplevel that is the largest level, the smallest level, and all the Miplevel between the largest level and the smallest level of the three Miplevel.
Taking the Mipmap texture region division shown in fig. 1 as an example, it is assumed that Mipmap texture region 1 corresponds to Miplevel1 and Miplevel2, mipmap texture region 2 corresponds to Miplevel2 and Miplevel3, and Mipmap texture region 3 corresponds to Miplevel1. As shown in fig. 2, mipmap texture region 1 in Miplevel1 and Miplevel2 is loaded, mipmap texture region 2 in Miplevel2 and Miplevel3 is loaded, and Mipmap texture region 3 in Miplevel1 is loaded.
In the embodiment of the disclosure, by way of example and not limitation, the determining the Mipmap area to which each texture coordinate belongs includes: comparing each texture coordinate with the texture coordinate range of the Mipmap texture region; and determining the Mipmap texture region with the texture coordinates falling into the texture coordinate range as the Mipmap texture region to which the texture coordinates belong.
Wherein, the texture coordinate range of the Mipmap texture area is determined according to the original resolution in the Mipmap texture. Assume that the texture coordinate range of a certain Mipmap texture region is as follows: (U0 min, V0 min), (U0 max, V0 max), for a certain texture coordinate (U, V), if U0min < U0max and V0min < V0max, the texture coordinate falls into the Mipmap texture region (i.e. the Mipmap texture region covers the texture coordinate, i.e. the Mipmap texture region is the Mipmap texture region to which the texture coordinate belongs), otherwise the texture coordinate does not fall into the Mipmap texture region.
Wherein, (U0 min, V0 min), (U0 max, V0 max) are texture coordinates on the texture map of the original resolution in the Mipmap texture.
The disclosed embodiments do not limit the division of Mipmap texture regions. In some embodiments, the partitioning is performed by software, and in other embodiments, the partitioning is performed by hardware in the GPU. In some embodiments, the Mipmap texture is divided equally into several Mipmap texture areas. In other embodiments, a partitioning policy is formulated according to requirements, actual rendering characteristics, etc., and the Mipmap texture is partitioned into a plurality of Mipmap texture regions according to the formulated partitioning policy. By way of example and not limitation, the Mipmap texture is divided into a plurality of regions according to distance to the camera.
If the Mipmap texture is divided into a plurality of regions by the GPU hardware according to the distance to the camera. In some embodiments, the graphics processor may further include a region partitioning module configured to: dividing a Mipmap texture region according to each texture coordinate and the Miplevel corresponding to the texture coordinate, wherein the proportion of target texture coordinates in the same Mipmap texture region reaches a set threshold value, and the target texture coordinates comprise texture coordinates corresponding to the same Miplevel.
The specific partitioning strategies are various, and in practical application, the specific partitioning strategies can be determined according to the actual rendering conditions or rendering requirements. By way of example and not limitation, in some embodiments, texture coordinates of a texture map of an original resolution in a Mipmap texture are grouped, the same set of texture coordinates corresponds to the same Miplevel in an image frame, and any one of the same set of texture coordinates is adjacent to at least one texture coordinate in the present set, each set of texture coordinates comprising a Mipmap texture region. In other embodiments, the texture coordinates of the original resolution texture map in the Mipmap texture are traversed, each traversal going to a texture coordinate, determining whether the texture coordinate is classable into an existing group, if the texture coordinate corresponds to the same Miplevel in the image frame as most of the texture coordinates in a group and is adjacent to at least one texture coordinate in the group, then the texture coordinate is classed into the group, otherwise, determining whether the texture coordinate falls within the texture coordinate range (Umin, vmin), (Umax, vmax) of the existing group, if so, then the texture coordinate is classed into the group, otherwise, creating a new group, and classing the texture coordinate into the new group. After the traversal is completed, the texture coordinates in each group form a Mipmap texture region. In one group, there are n texture coordinates corresponding to one Miplevel, m texture coordinates corresponding to another Miplevel, and p texture coordinates corresponding to another Miplevel, where the number of n is the largest, then these n texture coordinates are referred to as majority texture coordinates.
On the basis of any embodiment, the determining, according to the input pixel coordinates and texture coordinates, the Miplevel corresponding to each texture coordinate may include: and determining the corresponding Miplevel of each texture coordinate in each layer according to the pixel coordinates and the texture coordinates of each layer in the input three-dimensional space. Correspondingly, determining the Mipmap texture region to which each texture coordinate belongs, and the specific implementation manner may include: and respectively determining the Mipmap texture region to which each texture coordinate in each layer belongs. Correspondingly, the Miplevel information and the Mipmap texture area information in each layer are output to the texture loading software, so that the texture loading software respectively determines the Mipmap texture area corresponding to each Mipmap texture area in each layer according to the Miplevel information and the Mipmap texture area information of each layer, and loads the Mipmap texture area corresponding to the Mipmap texture area.
That is, the embodiments of the present disclosure may be applied to three-dimensional texture processing. The Mipmap texture area division mode of each layer can be different.
In some embodiments, the GPU may not include a texture tile determination module, and the functionality implemented by the texture tile determination module is implemented by texture loading software. The implementation principle of determining the Mipmap texture region to which each texture coordinate belongs by the texture loading software may refer to the description of the above embodiment, and will not be described herein.
Embodiments of the present disclosure also provide a graphics processing system including a graphics processor as described in any of the embodiments above.
Optionally, a processor may be further included in the graphics processing system, the processor configured to: and executing the texture loading software.
In an embodiment of the present disclosure, a product form of the graphics processing System may be an SOC (System on Chip) Chip.
By way of example and not limitation, for a mobile end product, the aforementioned processor may be included in its SOC chip.
The graphics processor system in the embodiments of the present disclosure may be a single die SOC chip or a multi die interconnect SOC chip.
The architecture and the working principle of the graphics processing system provided in the present disclosure are described below by taking one die as an example.
In one embodiment shown in FIG. 3, a single die graphics processing system includes a GPU core, i.e., the graphics processor described above.
The GPU core is used to process drawing instructions, and according to the drawing instructions, execute Pipeline of image rendering, and can also be used to execute other operation instructions. The GPU core further includes: the computing unit is used for executing instructions compiled by the shader, belongs to a programmable module and consists of a large number of ALUs; a Cache (Cache) for caching GPU-kernel data to reduce access to memory; a rasterization module, a fixed stage of the 3D rendering pipeline; a block division (tiling) module, wherein the TBR and TBDR GPU architectures perform block division processing on a frame; the clipping module clips out primitives which are outside the observation range or are not displayed on the back surface at a fixed stage of the 3D rendering pipeline; the post-processing module is used for performing operations such as zooming, cutting, rotating and the like on the drawn graph; microcores (microcores) for scheduling between various pipeline hardware modules on a GPU core, or for task scheduling for multiple GPU cores.
The GPU core is connected to a network on chip. Wherein the network-on-chip is used for data exchange between various masters and slaves (salves) on the graphics processing system, in this embodiment the network-on-chip includes a configuration bus, a data communication network, a communication bus, and so on.
As shown in fig. 3, the graphics processing system may further include:
a general purpose DMA (Direct Memory Access ) for performing data movement between the host side to a graphics processing system memory (e.g., graphics card memory), such as moving vertex (vertex) data of a 3D drawing from the host side to the graphics processing system memory via DMA;
the PCIe controller is used for realizing PCIe protocol through the interface communicated with the host, so that the graphics processing system is connected to the host through the PCIe interface, and programs such as a graphics API, a driver of a display card and the like are run on the host;
the application processor is used for scheduling tasks of each module on the graphic processing system, for example, the GPU is notified to the application processor after rendering a frame of image, and the application processor is restarted to display the image drawn by the GPU on a screen by the display controller;
the memory controller is used for connecting memory equipment and storing data on the SOC;
a display controller for controlling the frame buffer in the memory to be output to the display by a display interface (HDMI, DP, etc.);
Video decoding, which can decode the coded video on the host hard disk into pictures capable of being displayed;
the original video code stream on the hard disk of the host can be coded into a specified format and returned to the host.
Based on the graphics processing system architecture shown in FIG. 3, in one embodiment, the graphics rendering process is as follows:
the graphics API of the host sends a drawing instruction to the SOC chip, the drawing instruction can carry the Mipmap texture region division information, and the drawing instruction is required to render the image frame.
In this embodiment, the Mipmap texture is divided into three regions as shown in fig. 1.
The general DMA transfers vertex data (vertex data includes 3D coordinates of vertices of objects) of each object in the image frame from the host side to the graphics processing system memory.
And after the computing unit of the GPU core acquires the drawing instruction, decoding the drawing instruction.
The vertex shader of the GPU core (whose function is implemented by the computing unit) obtains vertex data of each object in the image frame from the system memory, and transmits the vertex data of the object to the geometry shader (whose function is implemented by the computing unit), which converts the 3D coordinates of the object vertices into expanded texture coordinates (i.e., (u, v) coordinates).
After the geometric processing is finished, a block dividing module in the GPU core carries out block dividing processing on objects in image frames, and a block dividing processing result is stored in a block buffer area and comprises a primitive index of primitives covering the blocks.
And after the block division is finished, the rasterizing module performs rasterizing processing. The rasterizing module processes the blocks one by one, and reads the primitive index of the primitive covering the current block from the block buffer each time; the rasterizing module reads the primitive information of the primitive through the primitive index, and performs a pixel coverage test using the primitive information of the primitive to determine a pixel covered by the primitive, and then performs a pixel interpolation calculation and at least one pixel test (by way of example and not limitation, the pixel test may include a depth test, a template test, etc.).
In the present disclosure, pixel coverage testing, pixel interpolation calculation, and pixel testing are implemented using existing techniques.
After the rasterization process is completed, the fragment shader of the GPU core (whose function is implemented by the computing unit) performs shading calculations (e.g., illumination calculations) for the corresponding pixels.
In the mapping processing stage, a multi-stage gradually-distant level determining module (the function of which is realized by a computing unit) determines the Miplevel corresponding to each texture coordinate according to the input pixel coordinates and texture coordinates, and outputs Miplevel information indicating the Miplevel corresponding to each texture coordinate. The texture block determining module (the function of which is realized by the computing unit) determines the Mipmap texture region to which each texture coordinate belongs by comparing each texture coordinate with the coordinate range of each Mipmap texture region, and outputs Mipmap texture region information indicating the Mipmap texture region to which each texture coordinate belongs.
In practical application, the graphics API (in the graphics processing system of the mobile terminal, texture loading software on an application processor) determines texture coordinates respectively covered by each Mipmap texture area according to the Mipmap texture area information, and determines Miplevel corresponding to the texture coordinates covered by each Mipmap texture area according to the Mipmap texture information.
In this embodiment, mipmap texture region 1 corresponds to Mipmap 1 and Mipmap 2, mipmap texture region 2 corresponds to Mipmap 2 and Mipmap 3, and Mipmap texture region 3 corresponds to Mipmap 1.
The graphics API loads the multi-level progressive texture region of the corresponding mipevel. As shown in fig. 2, mipmap texture region 1 in Miplevel1 and Miplevel2 is loaded, mipmap texture region 2 in Miplevel2 and Miplevel3 is loaded, and Mipmap texture region 3 in Miplevel1 is loaded.
