Abstract:
Generation of a clock signal in a semiconductor integrated circuit (IC) is controlled using a Noise Modulation Agent (NMA), configured to measure the clock signal and output a parameter indicative of an effective cycle time of the clock signal. An Adaptive Frequency Scaling (AFS) circuit selectively adjusts a frequency of the clock signal, based on the output of the NMA indicating a change in a power supply voltage of the semiconductor IC.
