Abstract:
A method and apparatus for providing proactive current protection. In one embodiment, the method comprises: prior to transitioning to a new state for an integrated circuit (IC), calculating a sum of expected powers for a plurality of domains in the IC by calculating an expected current for each of the plurality of domains based on an individual domain frequency in the new state and multiplying the expected current with its associated voltage for each of the plurality of domains for the new state; comparing the sum to a power limit; and if the sum is greater than the power limit, then reducing the individual domain frequency associated with at least one domain in the plurality of domains to maintain the total instantaneous power of the IC below the power limit.
