Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tile-based three-dimensional (3D) rendering methods using a single core or the same number of cores as tiles result in suboptimal performance and resource utilization, leading to inefficient processing and high costs.
Innovation Solution
A system and method utilizing a multi-core processor with a configuration of dual cores, scratch pad memory, and shared memory, allowing data to be distributed and processed in predetermined modes such as VLIW and CGA, and employing double-buffering to prevent redundant processing and enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single core or the same number of cores as tiles is used for rendering, then the device complexity is reduced, but the productivity and resource utilization are insufficient
Solution Approach 1:
The screen is divided into multiple tiles, and each tile is assigned to a specific core for independent rendering. This segmentation allows parallel processing across multiple cores, significantly improving rendering performance while maintaining manageable complexity through modular architecture
Solution Approach 2:
The multi-core processor is designed with universal rendering capabilities where each core can handle multiple rendering tasks including vertex processing, fragment processing, and tile rendering. This multi-functionality maximizes resource utilization across all cores
2Productivity
If data is processed without distribution across cores, then the device complexity is reduced, but redundant processing occurs and productivity decreases
Solution Approach 1:
Data is pre-distributed to appropriate cores before rendering begins. The system performs preliminary data preparation and allocation, ensuring each core receives the specific tile data it needs in advance, which eliminates redundant processing and improves processing efficiency
Solution Approach 2:
Tile data is copied to the frame buffer memory associated with each core. This copying mechanism ensures that each core has local access to the data it needs without requiring other cores to provide it, preventing redundant data retrieval operations
3Productivity
If frame buffer memory is not shared between cores, then device complexity is reduced, but resource utilization and productivity are limited
Solution Approach 1:
Frame buffer memories from multiple cores are merged into a shared frame buffer memory that all cores can access. This merging allows efficient resource utilization where processed tiles can be transferred to the final frame buffer through the shared memory architecture, improving overall system productivity
