Engineering Contradiction Analysis
1Adaptability or versatility
If a computing system uses processor cores with different instruction set architectures (ISAs) to improve adaptability and flexibility, then the system can handle diverse computational tasks more efficiently, but the complexity of managing data representation and execution across different ISAs increases
Solution Approach 1:
The patent introduces an intermediary layer (binary translation mechanism) that mediates between different ISAs. This intermediary translates binary representations from one ISA format to another, enabling processor cores with different ISAs to execute the same program without requiring complex per-core configuration management. The intermediary handles the complexity of ISA compatibility, allowing the system to maintain high adaptability while managing diversity through a standardized translation approach.
2Use of energy by moving object
If the system dynamically switches execution between processor cores with different performance characteristics to improve resource allocation flexibility, then power consumption is reduced, but the overhead of managing execution context switching increases
Solution Approach 1:
The patent implements preliminary action by pre-translating binary representations into multiple ISA formats before execution. This allows the system to have pre-prepared binary versions that can be quickly switched between different processor cores without requiring complex real-time translation during execution. The overhead is shifted to the compilation/translation phase rather than the runtime switching phase, reducing the time penalty of dynamic core selection while maintaining power efficiency.
3Device complexity
If the system uses a single binary representation format across all processor cores to simplify management, then device complexity is reduced, but computational efficiency and adaptability across different ISAs deteriorate
Solution Approach 1:
The patent applies universality by creating a multi-functional binary representation system where a single binary file can be executed on multiple different ISA architectures. The binary representation is designed to be universally compatible through translation mechanisms, allowing the same binary to serve multiple processor cores with different ISAs. This maintains simplicity in binary management while preserving computational efficiency by enabling optimal execution on the most suitable processor core for each task.
