GPU Texture Memory Allocation for Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display processes in mobile devices result in memory occupation waste and frame freezing due to the need for separate memory allocation for CPU and GPU, as well as time-consuming data conversion and uploading processes.
Innovation Solution
An image processing method that allocates memory directly to the GPU for storing texture data, eliminating the need for CPU memory allocation and performing parallel data conversion to generate texture data, thereby reducing memory waste and data uploading time.

Engineering Contradiction Analysis
1Reliability
If separate memory partitions are allocated for CPU and GPU, then each processor can access its own memory, but memory occupation waste occurs
Solution Approach 1:
The patent merges the memory allocation process by allowing the GPU to directly access the memory partition originally allocated for CPU bitmap data. This eliminates the need for separate memory partitions for CPU and GPU, reducing memory waste while maintaining access reliability for both processors.
Solution Approach 2:
The memory partition allocated for CPU bitmap data is made universally accessible to both CPU and GPU. This multi-functional memory allocation allows the same memory space to serve both processors, eliminating redundant memory occupation while ensuring reliable access for both CPU decoding and GPU rendering operations.
2Reliability
If bitmap data is converted to texture data and uploaded to GPU memory, then the GPU can perform drawing operations, but the process consumes significant time causing frame freezing
Solution Approach 1:
The patent performs preliminary action by pre-converting bitmap data to texture data format in advance, before GPU rendering is needed. This allows the GPU to directly use the pre-converted texture data without waiting for conversion during the critical rendering path, significantly reducing frame freezing while ensuring reliable drawing operations.
Solution Approach 2:
The patent maintains continuity of useful action by overlapping the bitmap-to-texture conversion process with other non-critical operations. The conversion continues in the background while other tasks execute, ensuring the GPU always has available texture data without interruption, thus eliminating frame freezing while maintaining continuous productive work.

AI summary
A method includes: displaying an interaction interface of an application, and when a preset operation performed by a user on the interaction interface is detected, decoding to-be-displayed image data of the application into bitmap data, and encapsulating the bitmap data into texture data; storing the texture data in a memory partition accessible to a graphics processing unit GPU; triggering the GPU to read the texture data and perform drawing processing to obtain rendered data; and triggering a display to display an image based on the rendered data.
