1Reliability
If fixed-function circuits are used, then system reliability is improved, but system adaptability deteriorates
Solution Approach 1:
The system is divided into multiple reconfigurable logic blocks that can be independently configured and connected through programmable interconnect structures. This segmentation allows different portions of the system to be optimized for specific functions while maintaining overall adaptability through reconfiguration capability.
Solution Approach 2:
The patent implements dynamic reconfiguration capability where the logic blocks and interconnect structures can be programmed and reprogrammed at runtime. This dynamic nature allows the system to adapt its functionality based on operational requirements while maintaining stable, reliable operation within each configured state.
2Ease of operation
If microcontroller intervention is used for reconfiguration, then system control flexibility is improved, but processing load and operation time worsen
Solution Approach 1:
The system incorporates autonomous control capability where reconfigurable logic blocks can be configured and controlled independently of the main microcontroller. This self-service mechanism allows critical reconfiguration operations to occur without burdening the microcontroller, reducing processing load and operation time while maintaining control flexibility through programmable interfaces.
3Adaptability or versatility
If programmable blocks are used, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The patent employs universal reconfigurable logic blocks that can perform multiple functions through programming rather than requiring dedicated hardware for each function. This multi-functionality approach increases adaptability while managing device complexity by using standardized, reusable building blocks with programmable interconnect structures.
