Engineering Contradiction Analysis
1Productivity
If the microprocessor operates at higher clock frequency to increase performance, then the performance is improved, but the power consumption increases
Solution Approach 1:
The microprocessor dynamically adjusts its operating voltage and frequency based on real-time temperature conditions. The control circuit continuously monitors temperature and automatically transitions between different operating states (first state at higher voltage/frequency for cooling temperatures, second state at lower voltage/frequency for elevated temperatures), enabling the system to optimize performance while minimizing power consumption under varying thermal conditions
Solution Approach 2:
The invention changes the operating parameters (voltage and frequency) of the microprocessor based on temperature conditions. By switching between a first operating voltage and a second operating voltage (lower than the first), and corresponding frequency states, the system adapts its electrical parameters to balance performance requirements with power consumption constraints under different thermal environments
2Productivity
If traditional overclocking is used to increase performance, then the performance is improved, but the reliability deteriorates
Solution Approach 1:
The control circuit continuously monitors the temperature of the microprocessor and uses this feedback to automatically adjust operating parameters. This closed-loop control ensures the microprocessor operates within safe thermal boundaries, preventing the reliability issues associated with traditional overclocking while still enabling performance optimization when conditions permit
Solution Approach 2:
The microprocessor system performs self-regulation of its operating parameters based on internal temperature monitoring. The control circuit automatically transitions between operating states without external intervention, adjusting voltage and frequency to maintain reliable operation while maximizing performance within thermal constraints
3Use of energy by moving object
If the operating voltage is reduced to decrease power consumption, then the power consumption is reduced, but the performance deteriorates
Solution Approach 1:
The system dynamically selects between different voltage and frequency operating points based on real-time temperature conditions. When temperatures are low, the microprocessor operates at higher voltage and frequency for maximum performance. When temperatures rise, it automatically transitions to lower voltage and frequency states to reduce power consumption, creating a dynamic balance between performance and energy efficiency
4Reliability
If thermal monitoring mechanisms are implemented to protect the microprocessor, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The microprocessor incorporates an integrated temperature sensor and control circuit that automatically monitors thermal conditions and adjusts operating parameters without external intervention. This self-regulating mechanism provides robust thermal protection while minimizing the need for additional external monitoring components, thereby limiting the increase in overall system complexity

AI summary
A microprocessor capable of dynamically reducing its power consumption based on its varying operating temperature includes a temperature sensor that monitors the microprocessor's operating temperature and a control circuit that includes operating point data. The operating point data includes, for each of a plurality of frequencies, a first voltage at which the microprocessor may reliably operate at a frequency and at a first temperature, and a second voltage at which the microprocessor may reliably operate at the frequency and at a second temperature. The second temperature is less than the first temperature and the second voltage is less than the first voltage. The control circuit causes the microprocessor to operate at the frequency and at the second voltage rather than at the first voltage when the operating temperature drops below the second temperature while operating at the frequency and at the first voltage.
