Abstract
A data processing system includes a power manager for providing a power event depth signal in response to a power event request signal. A plurality of real-time clients is coupled to the power manager. Each real-time client includes a client buffer that has a plurality of entries for storing data. The real-time client also includes a register for storing a watermark threshold for the client buffer, as well as logic for providing an allow signal when a number of valid entries in the client buffer exceeds the watermark threshold. A power management state machine is coupled to each of the plurality of real-time clients. The power management state machine provides a power event start signal in response to all of the plurality of real-time clients providing respective allow signals.
