A system and method for providing a digital real-time voltage droop detection and subsequent voltage droop reduction. A scheduler within a reservation station may store a weight value for each instruction corresponding to node capacitance switching activity for the instruction derived from pre-silicon power modeling analysis. For instructions picked with available source data, the corresponding weight values are summed together to produce a local current consumption value and this value is summed with any existing global current consumption values from corresponding schedulers of other processor cores yielding an activity event. The activity event is stored. Hashing functions within the scheduler are used to determine both a recent and an old activity average using the calculated activity event and stored older activity events. Instruction issue throttling occurs if either a difference between the old activity average and the recent activity average exceed a first threshold or the recent activity average exceeds a second threshold.

A parent provides information regarding a child and other family members to a system. The information is then used to create customized assemblages of linear and interactive media, which may be further personalized for that child's entertainment and education. The customized and personalized episode so assembled persists and can be replayed indefinitely. New episodes are created regularly (e.g., daily), and can be based on the child's age, preferences, and performance while experiencing previous episodes. Scheduled events (e.g., birthdays, starting school), local current events (e.g., weather), the current situation (e.g., current location, time of day), etc. may also influence the creation of new episodes. While monitoring the child's progress, the system provides to a parent suggestions for activities related to the child's recent episodes.
