Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users directly program FPGA hardware using manufacturer tools and project frameworks, then full customization and optimization capability is achieved, but specialized expert knowledge is required and implementation time becomes very long
Solution Approach 1:
The FPGA is divided into two distinct sections: a static section containing preset logic developed by experts, and a dynamic section that users can reconfigure. This segmentation allows users to customize the dynamic section without needing to program the entire FPGA, significantly reducing implementation time while maintaining customization capability for the dynamic portion.
Solution Approach 2:
Expert-optimized logic is pre-configured in the static section of the FPGA during manufacturing. This preliminary action by experts eliminates the need for users to perform complex FPGA programming tasks, reducing implementation time from months to hours while preserving the benefits of expert optimization.
2Productivity
If expert-optimized logic is implemented in FPGA, then performance and efficiency are maximized, but any customization by non-expert users compromises optimization and requires complete reimplementation
Solution Approach 1:
By segmenting the FPGA into static and dynamic sections, the system preserves expert-optimized logic in the static section while allowing user customization in the dynamic section. This eliminates the need for complete reimplementation when users customize, as the static section remains intact and optimized.
Solution Approach 2:
Different sections of the FPGA have different qualities: the static section maintains expert-optimized performance characteristics, while the dynamic section provides user-configurable flexibility. This local differentiation allows both optimized performance and user customization to coexist without compromising either.
3Adaptability or versatility
If complete FPGA logic is reconfigured for every user customization, then full adaptability is achieved, but compilation and implementation times become prohibitively long
Solution Approach 1:
The segmentation of FPGA logic into static and dynamic sections enables independent configuration of each part. Users only need to compile and implement changes in the dynamic section, dramatically reducing compilation time compared to reconfiguring the entire FPGA logic for every customization.
Solution Approach 2:
Instead of requiring complete FPGA reconfiguration for every customization, the system applies partial action by allowing users to modify only the dynamic section. This partial configuration approach maintains sufficient adaptability while reducing compilation and implementation time from days to hours.
4Ease of operation
If graphical programming tools are used to simplify FPGA programming, then ease of use is improved, but performance is reduced due to lower optimization capability
Solution Approach 1:
The static section contains expert-optimized logic that achieves high performance, while the dynamic section uses simplified graphical programming tools for user customization. This segmentation allows the system to maintain high overall performance through the optimized static section while providing ease of use for user modifications in the dynamic section.
