The present disclosure relates to computational systems and methods related to nutraceuticals. For each phase waveform, a power system digital frequency may be determined through analysis of the first quadrature signal while eliminating waveform phase angles from the analysis. For a current block of an image being processed, motion vectors associated with blocks of the image being processed andor associated with blocks of a processed image are selected. The variable voltage power supply is coupled to the processor and delivers voltage to the processor.
