ABSTRACT:
A power monitor for electronic devices, such as computer chips, is used to estimate the power consumption and to compare the estimated power consumption against the power budget. The estimated power consumption is based on activity signals from various functional blocks of the computer chip. The activity signals that are monitored correlate accurately to the total number of flip-flops that are active at a given time. If the estimated power consumption exceeds the power budget, the speed of the clock signals supplied to the computer chip is reduced.
