In particular, a sampling window for the governor can switch between a first mode and a second mode, where the first mode involves a default sampling window having a period greater than 1/f, is out of phase with or not aligned with VSync pulses, and is clocked to an internal clock of the CPU frequency governor. The second mode involves an adjusted sampling window having a period equal to 1/f, and is in phase with or aligned with VSync pulses. Further, f, can be the refresh rate of a display device. VSync pulses can be provided to the CPU frequency governor, which can use these pulses to clock the sampling window when a CPU workload becomes or is expected to become sporadic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"VSync aligned CPU frequency governor sampling","description":"Systems, methods, and apparatus are herein described for reducing stuttering or skipped frames in media rendering by switching between two sampling windows of a CPU frequency governor.
