Solution Overview
Problem
Microprocessor designers face challenges in achieving optimal performance across various software applications due to the need to choose between configurations optimized for one application at the expense of others, as existing dynamic configuration methods do not fully address the diverse performance requirements of different software applications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the microprocessor is configured with a fixed configuration optimized for one software application, then the performance for that specific application is improved, but the performance for other software applications deteriorates
Solution Approach 1:
The patent implements dynamic reconfiguration of functional units based on real-time detection of instruction sequences. The microprocessor transitions from static configuration to dynamic configuration, allowing operational characteristics to change during execution based on detected software patterns, thus resolving the contradiction between optimized performance and adaptability
Solution Approach 2:
The fingerprint detection unit continuously monitors executed instructions and provides feedback about detected software applications. This feedback mechanism enables the system to automatically adjust configuration settings based on actual runtime conditions, achieving both high performance for detected applications and adaptability to new applications
2Adaptability or versatility
If the microprocessor includes multiple configuration settings to support different software applications, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent creates a universal detection and reconfiguration system that handles multiple software applications through a single fingerprint detection unit and unified reconfiguration mechanism. This multi-functional approach allows one system to serve multiple purposes (detecting different applications and switching configurations) without proportionally increasing complexity
Solution Approach 2:
The microprocessor automatically detects which software application is running and self-reconfigures without external intervention. The system serves itself by monitoring its own execution state and making configuration changes autonomously, reducing the complexity burden that would otherwise require external configuration management
3Productivity
If the microprocessor dynamically reconfigures functional units during execution, then the performance optimization is improved, but the loss of time due to reconfiguration overhead increases
Solution Approach 1:
The patent pre-computes and stores fingerprints for known software applications before runtime. When execution begins, the system only needs to compare incoming instruction sequences against these pre-computed fingerprints rather than performing complex analysis, significantly reducing the time penalty of dynamic detection and reconfiguration

AI summary
A microprocessor includes a plurality of dynamically reconfigurable functional units, a fingerprint, and a fingerprint unit. As the plurality of dynamically reconfigurable functional units execute instructions according to a first configuration setting, the fingerprint unit accumulates information about the instructions according to a mathematical operation to generate a result. The microprocessor also includes a reconfiguration unit that reconfigures the plurality of dynamically reconfigurable functional units to execute instructions according to a second configuration setting in response to an indication that the result matches the fingerprint.
