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.
