Zusammenfassung:A data scaling module for USB4 that embodies display driver (DD) and connection manager (CM) operations. Periodic and aperiodic transfer requests are monitored. The periodic BW activity on periodic peripherals, such as display panels (DPs) is monitored, and determinations as to reduced periodic activity on a DP are made. Responsive to receiving a high aperiodic bandwidth request, the original refresh rate for the DP is reduced. The newly freed USB4 BW is provided for the aperiodic task. At completion of the aperiodic task, the DD increases the refresh rate to its original value.
