Abstract: Clock enable signals are collected and summed. The number of simultaneously enabled clock enable signals can represent switching activity within a system and can be used as an indicator for power management, noise management, etc. of such a system. Digital switching activity sensing include performance of an operation to sum a quantity of open clock gates associated with a plurality of latches that are grouped into multiple subsets of latches. An activity indication is generated based, at least in part, on a result of the operation to sum the quantity of open clock gates associated with the plurality of latches.
