1. A video processing device comprising:
- a substrate;
a plurality of ring oscillators coupled to the substrate, the plurality of ring oscillators generating a corresponding plurality of ring oscillator outputs, wherein the plurality of ring oscillators are distributed along a plurality of rows and columns of the substrate;
a control circuit, coupled to monitor the plurality of ring oscillator outputs, that generates power adjustment signals for adjusting at least one power supply voltage of the video processing device, based on the plurality of ring oscillator outputs; and
a column decoder and a row decoder, coupled to the control circuit and the plurality of ring oscillators, that couple a selected one of the plurality of ring oscillator outputs to the control circuit in response to a row and column address.
