Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional graphics processing resources are used for deep learning operations, then general graphics rendering can be maintained, but processing speed and efficiency for deep learning tasks are insufficient
Solution Approach 1:
The graphics processor is segmented into dedicated functional units: tensor cores for matrix operations, ray tracing cores for visibility queries, and traditional rasterization units. This segmentation allows each unit to be optimized for its specific function, enabling deep learning operations to execute at higher speeds without requiring excessive overall processing power.
Solution Approach 2:
A cache streaming apparatus is introduced as an intermediary component between memory and processing units. This apparatus includes cache memory and streaming multiprocessors that pre-process and manage data flow, reducing the computational burden on main processing units and improving overall system efficiency for deep learning tasks.
2Productivity
If more processing resources are allocated to deep learning tasks, then deep learning performance improves, but resource availability for other graphics operations decreases
Solution Approach 1:
The graphics processor is designed with universal processing capabilities where tensor cores can handle both deep learning matrix operations and traditional graphics computations. Ray tracing cores can serve both real-time rendering and deep learning inference tasks. This multi-functionality allows the system to maintain high deep learning performance while preserving resource availability for other graphics operations.
Solution Approach 2:
The processor implements dynamic resource allocation where the cache streaming apparatus and various cores can be dynamically configured based on workload requirements. The system can switch between different operational modes (e.g., deep learning-optimized mode, graphics-optimized mode, or hybrid mode) to balance resource allocation according to current task demands.
3Speed
If memory management is optimized for deep learning workloads, then processing speed increases, but memory bandwidth for other operations may be limited
Solution Approach 1:
The cache streaming apparatus performs preliminary data processing and pre-fetching operations. Streaming multiprocessors prepare data in advance by loading it into cache memory before main processing units need it. This preliminary action accelerates data access speed for deep learning operations while managing memory bandwidth through intelligent pre-processing and caching strategies.
