Abstract
Systems and methods for dynamic clock and voltage scaling can switch integrated circuits between frequency-voltage modes with low latency. These systems include a resource power manager that can control a power management integrated circuit (PMIC), phase locked loops (PLLs), and clock dividers. The resource power manager controls transitions between frequency-voltage modes. The systems and methods provide dynamic clock and voltage scaling where the transitions between frequency-voltage modes are an atomic operation. Additionally, the resource power manager can control many modules, for example, clock dividers, in parallel. The invention can, due to lower latency between frequency-voltage modes, can provide improved system performance and reduced system power.
