摘要： A dynamic performance circuit adjustment system and method that flexibly adjusts the performance of a logic circuit. The dynamic performance circuit adjustment system and method facilitates flexible power conservation. In one exemplary implementation, a dynamic performance adjustment control circuit controls performance adjustments to a logic circuit (e.g., a processor) and adjusts support functions for the logic circuit. The logic circuit performs operational functions (e.g., processing) or tasks that have different performance requirements. For example, some tasks performed by the logic circuit are required to be performed in a relatively short duration of time and other tasks performed by logic circuit have relatively longer time limitations. The dynamic performance adjustment control circuit adjusts the clock frequency and voltage at which the logic circuit operates to a relatively greater frequency and voltage for tasks required to be performed in a shorter duration of time and adjusts the frequency and voltage at which the logic circuit operates to a relatively lower frequency and voltage for tasks with longer timing tolerances. The dynamic performance adjustment system and method includes provisions to manage a transition in performance and support functions in a manner that reduces the risk of spurious signals or “glitches.”
