Abstract: A system and method for efficient management of operating modes within an integrated circuit (IC) for optimal power and performance targets. A semiconductor chip includes one or more processing units each of which operates with respective operating parameters. One or more temperature sensors are included to measure a temperature of the one or more processing units during operation. When the measured temperature exceeds a threshold, a power manager on the chip determines a temperature headroom utilizing temperature values based on worst-case ambient temperature. When the measured temperature does not exceed the threshold, the power manager determines the temperature headroom utilizing at least one temperature value based on room ambient temperature. Following, the power manager adjusts the respective operating parameters based on at least the temperature headroom.
Abstract translation: 一种用于在集成电路（IC）内高效管理工作模式以实现最佳功率和性能目标的系统和方法。 半导体芯片包括一个或多个处理单元，每个处理单元以各自的操作参数进行操作。 包括一个或多个温度传感器以测量操作期间一个或多个处理单元的温度。 当测量温度超过阈值时，芯片上的电源管理器使用基于最坏情况环境温度的温度值来确定温度上升空间。 当测量的温度不超过阈值时，功率管理器使用基于室内环境温度的至少一个温度值来确定温度净空。 以下，功率管理器至少基于温度上升空间来调节相应的操作参数。
