Abstract: Systems, apparatuses, and methods for reaching power targets across different clock domains are described. In various embodiments, a first processor complex and a second processor complex operate while powered by a same, single power plane, but with respective clock domains. When a request is detected to change an operating mode of a particular core from one of the processor complexes to an operating mode which does not provide the worst-case power supply load on the single power plane, an amount of voltage margin to recover from the operational voltage is determined based on the second operating mode prior to granting the request and based on each other core in the complexes operating in respective current operating modes. An operational voltage less the determined voltage margin to recover is assigned to the processor complexes while different clock frequencies are assigned to the processor complexes.

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.

Abstract: In an embodiment, a digital power estimator (DPE) may be provided that may monitor the processors to estimate the amount of power being consumed. If the estimate exceeds a power threshold, the DPE may throttle one or more of the processors. Additionally, throttling events may be monitored to determine if a change in the operating point is desired. In one embodiment, the DPE throttling events may be counted, and if the counts exceed a count threshold, a change in the operating point to a reduced operation point may be requested. Additionally, if the DPE estimate is below the power threshold (or a second power threshold), a second count of events may be maintained. If the second count exceeds a threshold and the operating point is the reduced operating point, a return to the original operating point may be requested.
