More Information
Summary:A clock management unit (CMU) includes a first clock control circuit controlling a first clock source, a second clock control circuit sending a first clock request to the first clock control circuit in response to an intellectual property (IP) block clock request from an IP block and controlling a second clock source, and a CMU controller. The second clock control circuit receives a clock signal from the first clock source. A power management unit (PMU) sends a PMU clock request to the CMU controller. The CMU provides the clock signal to the IP block in response to the PMU clock request.
