Solution Approach 1:

The patent changes the operating voltage parameter dynamically based on temperature conditions. At lower temperatures, the microprocessor operates at reduced voltage to minimize power consumption, while at higher temperatures, it operates at full voltage to support maximum frequency and performance. This parameter adjustment resolves the contradiction by optimizing the voltage-frequency-power relationship according to thermal conditions.

Solution Approach 1:

The patent implements dynamic adjustment of operating frequency based on real-time temperature conditions. Rather than maintaining a fixed high frequency, the processor adapts its frequency dynamically - operating at maximum frequency when temperatures are low and automatically reducing frequency when temperatures rise, thereby maintaining performance optimization without excessive thermal accumulation.

AI summary

A temperature sensor in a microprocessor monitors its operating temperature Operating point data includes a first temperature being the maximum temperature at which the microprocessor will reliably operate at a first frequency and first voltage, the first frequency being the maximum frequency at which the microprocessor will reliably operate at the first temperature and the first voltage. Operating point data also includes a second temperature at which the microprocessor will reliably operate at a second frequency and a second voltage, the second frequency being greater than the first frequency and the second temperature less than the first temperature. A control circuit causes the microprocessor to operate at the second voltage and frequency rather than the first voltage and frequency in response to detecting that while operating at the first voltage and the first frequency the operating temperature dropped below the second temperature.
