Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different types of hardware are required to recognize different types of code fingerprints, then the recognition capability for specific fingerprint types is improved, but the device complexity and adaptability to new fingerprint types deteriorate
Solution Approach 1:
The patent implements a universal hardware architecture using field-programmable logic that can be configured to recognize multiple types of code fingerprints through software descriptions. Instead of requiring separate hardware for each fingerprint type, a single reconfigurable logic unit handles diverse fingerprint recognition tasks by loading different configuration descriptions, thereby reducing hardware complexity while maintaining comprehensive recognition capability
Solution Approach 2:
The system employs dynamic reconfiguration of programmable logic devices at runtime or predefined times based on the specific fingerprint recognition task required. The hardware can be reprogrammed to adapt to new fingerprint types or behavioral patterns, allowing the system to transition from static hardware design to dynamic adaptive architecture, resolving the contradiction between specialized recognition capability and hardware complexity
2Reliability
If fixed hardware is used for fingerprint recognition, then the recognition of supported fingerprints is reliable, but the adaptability to rapidly changing technology and new fingerprint types deteriorates
Solution Approach 1:
The patent transforms fixed hardware into a dynamic system by implementing field-programmable logic that can be reconfigured at runtime or predefined times. The programmable logic device maintains reliable recognition of established fingerprint types while allowing runtime reconfiguration to adapt to new fingerprint types and behavioral patterns, effectively resolving the contradiction between reliability and adaptability
Solution Approach 2:
The system changes the operational parameters of the hardware by loading different configuration descriptions into the programmable logic. These parameter changes allow the same physical hardware to recognize diverse fingerprint types including branch prediction hits/misses, cache hits/misses, and other processor behaviors, maintaining reliability through structured configuration while achieving adaptability through parameter reconfiguration
3Adaptability or versatility
If multiple hardware types are deployed for comprehensive fingerprint recognition, then the coverage of fingerprint types is improved, but the system flexibility and ease of operation deteriorate
Solution Approach 1:
The patent consolidates multiple hardware types into a single universal programmable logic platform. The runtime environment compiles descriptions of desired fingerprint recognition capabilities and loads them into the programmable logic, providing comprehensive fingerprint type coverage while simplifying system operation to a software-based configuration process rather than hardware assembly
Solution Approach 2:
The system uses software descriptions that replicate the functionality of specialized hardware in a virtualized form. These descriptions are compiled and loaded into the programmable logic, allowing the system to achieve comprehensive fingerprint recognition coverage through software configuration rather than physical hardware deployment, thereby improving ease of operation
