摘要： A method for conserving power begins by measuring processing speed of at least a portion of an integrated circuit (IC) to produce measured processing speed. The portion of the IC may be a test circuit, a critical path of the IC, and/or a replica of the critical path of the IC. The processing continues by comparing the measured processing speed with a critical processing speed for the at least a portion of the integrated circuit. The processing then continues by adjusting supply voltage to the integrated circuit to reduce power consumption of the integrated circuit when the measured processing speed compares favorably to the critical processing speed.

摘要： A system and method operable to automatically disable input/output signal processing based on the required data format is provided. The need for an input/output module, such as an encoder, required to process input signal having a first data format (i.e. multimedia format) and produce an output signal having a second format (i.e. multimedia format) is determined. When the input/output module is not required to produce the output signal in the second format, the input/output module is disabled.
