HOME       UP       PREV       NEXT (Power Modelling using
SystemC)    Dynamic Voltage Scaling  CMOS delay is inversely
proportional to supply voltage.  Voltage to a region may be
varied dynamically. A higher  Operating region of the
frequency/voltage curve is roughly linear.   Let's only raise
VCC when we ramp up f.     2. then adjust VCC so logic just
works.   Overall: power will then have cubic dependence on f. So
we achieve peak performance under heavy loads and avoid cubic
overhead when idle.   Power isolation is used on a longer and
larger scale (complete continents).
