微处理器能够根据变化的工作温度动态提高其性能

Microprocessor capable of dynamically increasing its performance in response to varying operating temperature
Abstract:
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.
Abstract(Chinese):

微处理器中的温度传感器监视其工作温度工作点数据包括第一温度，微处理器将以第一频率和第一电压可靠地运行的最高温度，第一频率是微处理器可靠运行的最大频率 在第一温度和第一电压。 工作点数据还包括第二温度，微处理器将以第二频率和第二电压可靠地操作第二温度，第二频率大于第一频率，第二温度小于第一温度。 响应于检测到在第一电压和第一频率下操作工作温度降至第二温度以下时，控制电路使微处理器以第二电压和频率而不是第一电压和频率工作。
