Abstract
A system and method for controlling performance and/or power based on monitored performance characteristics. Various aspects of the present invention may comprise an integrated circuit comprising a first circuit module that receives electrical power. A second circuit module may monitor one or more performance characteristics of the first circuit module and/or the integrated circuit. A third circuit module may, for example, determine power control information based at least in part on the monitored performance characteristic(s). The power control information may be communicated to power supply circuitry to control various characteristics of the electrical power. Various aspects of the present invention may also comprise an integrated circuit comprising a first module that monitors at least one performance characteristic of a first electrical device. The integrated circuit may also comprise modules that determine power control information based on the monitored performance characteristic(s) and communicate such power control information to power supply circuitry.
