Engineering Contradiction Analysis
1Adaptability or versatility
If traditional Von Neumann computer architecture is used, then general-purpose computing is achieved, but execution efficiency for highly-parallel applications deteriorates
Solution Approach 1:
The system employs dynamic reconfiguration of processor arrays, allowing the hardware architecture to change its configuration based on the specific computational task. This enables the same physical hardware to adapt between different parallel processing configurations, achieving both versatility and high efficiency for different application types without requiring multiple fixed architectures.
2Productivity
If coarse-grained reconfigurable architectures are used, then execution efficiency for highly-parallel applications is improved, but device complexity increases
Solution Approach 1:
The reconfigurable processor system implements a universal architecture that can be configured to perform multiple different computational functions. By using a set of basic processing elements that can be dynamically reconfigured through programming, the system achieves multi-functionality without requiring separate specialized hardware for each application type, thus managing complexity while maintaining high productivity.
3Productivity
If reconfigurable processors are integrated into heterogeneous systems, then performance for machine-learning applications is improved, but system complexity increases
Solution Approach 1:
The system introduces a reconfigurable processor as an intermediary computing resource between the host processor and storage devices. This intermediary can be dynamically configured to handle specific machine-learning workloads, providing specialized acceleration while maintaining a relatively simple integration interface through standard communication protocols and memory interfaces, thus improving performance without proportionally increasing system complexity.
Data Source
AI summary
A data processing system is presented that is configured as a server in a client-server configuration for executing applications that a client in the client-server configuration can offload as execution tasks for execution on the server. The data processing system includes a reconfigurable processor, a storage device that stores configuration files for the applications, and a host processor that is coupled to the storage device and to the reconfigurable processor. The host processor is configured to receive an execution task of the execution tasks with an identifier of an application from the client, retrieve a configuration file that is associated with the application from the storage device using the identifier of the application, configure the reconfigurable processor with the configuration file, and start execution of the application on the reconfigurable processor, whereby the reconfigurable processor provides output data of the execution of the application to the client.
