摘要： A system and method for meeting performance goals in an electronic system in an energy efficient manner. Various aspects of the present invention may comprise operating an electrical circuit at a current level of performance and a current level of energy efficiency by providing the electrical circuit with electrical power characterized by a current set of power characteristics (e.g., utilizing a power control module). The current level of performance may be determined (e.g., by a performance monitor) and compared to a desired level of performance (e.g., by the power control module). If the current level of performance is higher than the desired level of performance, then the electrical circuit may be operated at a next (e.g., lower) level of performance and a next (e.g., higher) level of energy efficiency by providing the electrical circuit with electrical power characterized by a next set of power characteristics.

摘要： Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. In addition, the PSE controller may detect and validate a compatible PD, determine a power classification signature for the validated PD, supply power to the PD, monitor the power, and reduce or remove the power from the PD when the power is no longer requested or required. During detection, if the PSE finds the PD to be non-compatible, the PSE can prevent the application of power to that PD device, protecting the PD from possible damage.
