1Productivity
If traditional fixed function computational units are used in graphics processors, then the system maintains simplicity and reliability, but the ability to perform cross channel operations efficiently is limited
Solution Approach 1:
The processor is divided into multiple processing channels (first processing channel and second processing channel), each capable of independent operation. This segmentation allows parallel processing of different data streams while maintaining modular simplicity in each channel's design.
Solution Approach 2:
The processing elements in each channel are designed to perform multiple operations including cross channel operations, intra channel operations, and various computational tasks. This multi-functionality enables the same hardware structure to handle diverse workloads without requiring specialized fixed function units for each operation type.
2Productivity
If parallel processing is increased using SIMD or SIMT architectures, then throughput is improved, but the complexity of coordinating multiple threads and data streams increases
Solution Approach 1:
The parallel processing system is segmented into distinct processing channels with dedicated processing elements. Each channel can execute threads independently, reducing the coordination overhead compared to fully integrated SIMT architectures while maintaining high parallel throughput through channel-level parallelism.
Solution Approach 2:
Cross channel operation units act as intermediary components that facilitate data exchange and coordination between processing channels. These intermediaries simplify the coordination complexity by providing standardized interfaces and mechanisms for inter-channel communication, reducing the burden on individual processing elements.
3Adaptability or versatility
If more processing elements are added to increase parallelism, then cross channel operation capability is improved, but the device complexity and resource requirements increase
Solution Approach 1:
Each processing element is designed with universal functionality to perform both intra channel operations and cross channel operations. This multi-functionality allows the system to achieve high cross channel operation capability without requiring separate dedicated hardware for each operation type, thereby controlling device complexity.
Solution Approach 2:
The patent merges the functionality of multiple processing elements into organized channels, where processing elements within a channel work together on related tasks. This merging approach achieves versatility in cross channel operations while reducing overall device complexity through functional integration and shared resources.
