Solution Overview
Problem
Existing programmable logic circuit devices require full reconfiguration region initialization to address abnormalities, which is inefficient and resource-intensive.
Innovation Solution
A programmable logic circuit device with a processor that detects abnormalities and changes connections between elements in reconfiguration regions using specific reconfiguration data, allowing for targeted reconfiguration without initializing entire regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full reconfiguration region initialization is performed to address abnormalities, then reliability is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The reconfiguration regions are divided into multiple segments, allowing the system to reconfigure only the affected segment when an abnormality is detected, rather than initializing the entire reconfiguration region. This segmentation enables partial reconfiguration, reducing the time and resources required while maintaining reliability.
Solution Approach 2:
Instead of performing complete reconfiguration of all reconfiguration regions, the system applies partial reconfiguration only to the specific region where the abnormality occurred. This partial action is sufficient to address the issue without the overhead of full reconfiguration, thereby reducing processing time and resource consumption.
2Reliability
If full reconfiguration region initialization is performed to address abnormalities, then reliability is improved, but resource usage and device complexity increase
Solution Approach 1:
By segmenting the reconfiguration regions, the system reduces the complexity of the reconfiguration process. Each segment can be managed and reconfigured independently, lowering the overall device complexity and resource requirements compared to managing a single large reconfiguration region.
Solution Approach 2:
The system applies reconfiguration resources and processing power locally to only the affected region rather than distributing them across the entire device. This local quality approach optimizes resource usage and reduces the apparent device complexity by focusing computational efforts where needed.
3Productivity
If targeted reconfiguration is implemented instead of full initialization, then productivity is improved, but ease of operation may deteriorate
Solution Approach 1:
The system implements self-service by automatically detecting abnormalities and triggering reconfiguration of the affected regions without requiring manual intervention. This automation maintains ease of operation while achieving high productivity through targeted reconfiguration.
Solution Approach 2:
The system uses feedback mechanisms to monitor the state of reconfiguration regions and automatically initiate reconfiguration when abnormalities are detected. This feedback-driven approach simplifies operation by removing the need for manual control while maintaining high productivity through responsive, targeted reconfiguration.
