Engineering Contradiction Analysis
1Productivity
If data streams are routed through multiple physical layer chips and processing units (south bridge, north bridge, CPU), then existing hardware infrastructure is utilized, but transmission efficiency deteriorates and delays increase
Solution Approach 1:
The patent extracts the data stream routing function from the traditional CPU and bridge chip infrastructure and relocates it to the graphics processing unit (GPU). By taking out the routing function from the conventional path and placing it in the GPU, the system eliminates the delays associated with data passing through multiple components while utilizing existing hardware resources.
Solution Approach 2:
The GPU is enhanced to perform multiple functions: traditional graphics processing plus physical layer data stream routing and transmission. This multi-functionality allows the GPU to handle both graphics tasks and network communication tasks, eliminating the need for separate dedicated routing hardware and reducing transmission delays.
2Productivity
If traditional routing through CPU and bridge chips is used, then hardware resources are utilized, but transmission path complexity increases
Solution Approach 1:
The patent merges the data stream routing function with the graphics processing function in the GPU. By combining these previously separate functions into a single processing unit, the system simplifies the transmission path architecture while maintaining efficient data stream handling capabilities.
3Productivity
If direct routing through GPU is implemented, then transmission efficiency improves, but hardware resource utilization changes
Solution Approach 1:
The system utilizes the GPU's existing hardware resources (memory buffers, thread processors) for data stream routing without requiring separate dedicated routing hardware. The GPU serves itself by using its own resources to handle both graphics processing and data transmission tasks, improving efficiency while avoiding additional hardware overhead.
