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: In an embodiment, a system may include multiple processors and an automatic power state controller (APSC) configured to switch the processors between various operating points. The operating points may be described by data programmed into the APSC, and the APSC may include a register that is programmable with a target operating point request identifying a target operating point for the processors from among the described operating points. The data describing the operating points may also include an indication of whether or not the number of processors that may be concurrently active at the operating point is limited. Based on the indication and the number of active processors, the APSC may override the requested operating point with a reduced operating point. In some embodiments, a digital power estimator (DPE) may monitor operation of the processors and may throttle the processors when high power consumption is detected.
