Problem
Current graphics chip technologies face challenges in achieving high-quality rendering while ensuring compatibility with older-generation programming languages and various video output formats, requiring advanced hardware and software integration with flexible adaptability.
Innovation Solution
A multi-graphics processor system comprising a first and second graphics processor, where data processed by the first processor is sent to the second for further processing, returned, and output as a video signal through a single channel, with the first processor handling security and format conversions, and the second processor integrated with high-speed memory access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple graphics processors are used to enhance rendering quality and performance, then rendering quality and performance are improved, but system configuration complexity increases
Solution Approach 1:
The rendering workload is segmented between two graphics processors: the first GPU handles security processing and format conversion, while the second GPU performs high-speed rendering operations. This segmentation allows each processor to specialize in specific tasks, improving overall rendering performance while maintaining a manageable system configuration through clear functional division.
2Manufacturing precision
If data is processed through multiple graphics processors, then rendering quality is enhanced, but data processing time may increase
Solution Approach 1:
Security processing and format conversion are performed as preliminary actions by the first graphics processor before the main rendering operation. This preliminary processing prepares the data in advance, allowing the second GPU to immediately process the pre-processed data without waiting, thereby reducing overall processing time while maintaining high rendering quality.
Solution Approach 2:
The system maintains continuous useful action by having the first GPU prepare data while the second GPU processes rendering operations simultaneously. The data flow between the two processors is optimized to ensure continuous processing without idle time, maintaining high rendering quality while minimizing processing delays.
3Device complexity
If a single video output channel is used, then system configuration is simplified, but video output flexibility is reduced
Solution Approach 1:
The first graphics processor is designed with multi-functionality, handling both security processing and format conversion tasks. This universal processor can adapt to different video output requirements by changing the format conversion parameters, providing video output flexibility through a single channel while keeping the system configuration simple.
4Speed
If the second graphics processor is integrated with video memory, then memory access speed is improved, but chip complexity increases
Solution Approach 1:
The second graphics processor integrates video memory directly onto the same chip, merging storage and processing functions. This integration eliminates external memory interface complexities and achieves high-speed memory access through short internal connections, while the increased chip complexity is offset by the elimination of separate memory components and their interconnections.

AI summary
A first GPU is provided with a digital video output terminal (134) (Vout terminal) for connection to an external source. A digital video signal output from the Vout terminal is provided to a display device via a HDMI. The first GPU (100) and a second GPU (200) are connected to each other via a data bus (140) for bidirectional data exchange. The second GPU (200) applies a predetermined rendering process on data provided from the first GPU (100) via a data input and output interface. The rendered data is returned to the first GPU (100) via the data input and output interface. The first GPU (100) processes the data returned from the second GPU (200) as necessary and outputs a digital video signal via the Vout terminal and the HDMI.
