Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication between multi-core processors and various processors in electronic devices lacks flexibility, with only one communication channel leading to suboptimal data transmission speed, real-time capability, and stability.
Innovation Solution
Implementing a plurality of communication channels between cores with distinct communication performances, allowing selection of the appropriate channel based on data type and current transmission needs to enhance flexibility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only one communication channel is used between cores, then device complexity is reduced, but data transmission speed, real-time capability, and stability deteriorate
Solution Approach 1:
The communication channel is segmented into multiple independent channels (first communication channel and second communication channel) with different functionalities. The first channel handles normal data transmission while the second channel provides backup and emergency communication, thereby improving transmission stability without requiring a completely complex new structure
Solution Approach 2:
The system changes the parameter of communication channel quantity from one to multiple, and further changes the parameter of channel priorities (with different priority levels). This allows the system to maintain reasonable complexity while significantly improving reliability through parameter optimization
2Productivity
If multiple communication channels with different performances are implemented, then data transmission flexibility and speed are improved, but device complexity increases
Solution Approach 1:
The system implements dynamic channel selection where the processor can adaptively choose which communication channel to use based on real-time transmission needs. Normal transactions use the first channel while emergency or high-priority data uses the second channel, providing dynamic flexibility without permanent complex infrastructure
Solution Approach 2:
Both communication channels are designed to handle data transmission between the same two cores, providing multi-functionality. The channels can be used independently or in combination, allowing the system to achieve high transmission speed for specific data types while maintaining a relatively simple overall structure
3Loss of time
If channel selection based on data type is implemented, then data transmission real-time capability is improved, but control complexity increases
Solution Approach 1:
The system performs preliminary classification of data into normal transactions and emergency/high-priority data before transmission begins. By pre-defining which channel each data type should use, the system reduces real-time decision complexity while maintaining fast transmission capability
