Abstract
An integrated circuit (IC) including unit power control, leakage reduction circuit for controllably reducing leakage power with reduced LdI/dt noise in the IC and, an activity prediction unit invoking active/dormant states in IC units. The prediction unit determines turn on and turn off times for each IC unit. The prediction unit controls a supply voltage select circuit selectively passing a supply voltage to a separate supply line at the predicted turn on time and selectively blocking the supply voltage at the predicted turn off time.
