If traditional CPU-based decoding is used, then decoding can be performed, but decoding efficiency is low and CPU resource consumption is high

Engineering Contradiction:

Improvedecoding efficiencyVSAvoidCPU resource consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the CPU-based decoding mechanism with a GPU shader-based decoding mechanism. The graphic card shader executes parallel decoding operations for compression texture blocks, substituting the traditional sequential CPU processing with parallel GPU processing, thereby improving decoding efficiency and reducing CPU resource consumption

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent divides the image decoding task into multiple compression texture blocks, with each block assigned to a separate work group in the graphic card shader. This segmentation enables parallel processing of multiple blocks simultaneously, significantly improving overall decoding efficiency while distributing the computational load

Inventive Principle:

Principle #1Segmentation

2Productivity

If parallel decoding is implemented, then decoding efficiency is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a graphic card shader as an intermediary component between the CPU and the decoding process. The shader acts as a mediator that handles the complex parallel decoding operations, allowing the CPU to remain simple while delegating the computationally intensive parallel processing tasks to the GPU shader infrastructure

Inventive Principle:

Principle #24Intermediary (Mediator)
