【Abstract】 To estimate the power consumption of digital circuits from RTL, a model abstracted from VHDL description is estimated by entropy from information theory, considering correlation of outputs concerned. A power estimation formula with correlation of outputs concerned is deduced. The formula sets up the relationship between entropy and power dissipation, and gives an accurate estimation of power.更多还原
