DEVICE FOR CONTROLLING THE POWER SUPPLY OF A COMPUTER

摘要

The invention relates to a device for controlling a computer (4) capable of being powered with a plurality of voltage levels, including a controller (2) arranged so as to receive charge data (Ci), deadline data (Ni), and instantaneous speed data (w) for said computer (4), in order to calculate a reference speed that enables said computer to run an amount of calculations drawn from the charge data (Ci) in a period drawn from the deadline data (Ni), and to calculate a control voltage level (V_lvl) and operating frequency (f_op) for said computer from said reference speed. At least one element from among the reference speed and the operating frequency (f_op) is calculated using the instantaneous speed data (w).
