Abstract: In an embodiment, an integrated circuit includes multiple instances of a component (e.g. a processor) and a control circuit. The instances may be configured to operate in various modes. Some of the modes are incapable of presenting a worst-case load on the power supply. The control circuit may be configured to monitor the instances and detect the modes in which the instances are operating. Based on the monitoring, the control circuit may request to recover a portion of the voltage margin established for worst-case conditions in the instances. If the instances are to change modes, they may be configured to request mode change from the control circuit. If the mode change causes an increase in the current supply voltage magnitude (e.g. to restore some of the recovered voltage margin), the control circuit may cause the restore and permit it to complete prior to granting the mode change.

Abstract translation: 在一个实施例中，集成电路包括组件（例如处理器）和控制电路的多个实例。 这些实例可以被配置为以各种模式操作。 一些模式不能在电源上呈现最坏的负载。 控制电路可以被配置为监视实例并检测实例正在操作的模式。 基于监视，控制电路可以请求恢复在实例中为最坏情况条件建立的电压余量的一部分。 如果实例要改变模式，则它们可以被配置为从控制电路请求模式改变。 如果模式改变导致当前电源电压幅度的增加（例如，恢复一些恢复的电压余量），则控制电路可以在授予模式改变之前导致恢复并允许其恢复。
