Abstract
An integrated circuit includes an operational circuit module receiving a supply voltage from a voltage regulator external to the integrated circuit, and an adaptive voltage scaling module to adjust the supply voltage based on performance characteristics of the operational circuit module. The adaptive voltage scaling module can include a performance monitoring module disposed on the integrated circuit and configured to generate at least an indicator corresponding to at least one performance characteristic of the operational circuit module. The adaptive scaling module can include a voltage requirement determination and voltage feedback generator module disposed on the integrated circuit and coupled to the performance monitoring module. The voltage requirement determination and voltage feedback generator module is configured to output a feedback voltage signal having a voltage level as a function of at least the indicator. The voltage regulator can regulate the supply voltage as a function of the feedback voltage signal.
