摘要： In a method for monitoring power consumption by a system within an integrated circuit, one or more software programs are executed on the system on a chip (SOC). While the program executes, power control settings of a plurality of functional units within the SOC may be adjusted in response to executing the one or more software programs, whereby power consumption within the SOC varies over time. The power control settings may be changed in response to explicit directions from the executing software, or may occur autonomously in response to load monitoring control modules within the SOC. A sequence of power states is reported for the plurality of functional units within the SOC. Each of the sequence of power states may include clock frequencies from multiple clock domains, voltage levels for multiple voltage domains, initiator activity, target activity, memory module power enablement, or power enablement of each of the plurality of functional units.
