    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.

    Abstract translation: 一种用于提供主动电流保护的方法和装置。 在一个实施例中,该方法包括:在转换到集成电路(IC)的新状态之前,通过针对多个域中的每个域计算预期电流来计算IC中多个域的预期功率之和 在新状态的单个域频率上,将预期电流与其相关联的电压乘以用于新状态的多个域中的每一个; 将总和与功率限制进行比较; 并且如果所述和大于所述功率极限,则减少与所述多个域中的至少一个域相关联的各个域频率,以将所述IC的总瞬时功率维持在所述功率极限以下。

    Abstract: Examples are disclosed for an integrated circuit (IC) device coupled to a battery-operated power supply unit, such as an IC in a mobile computing device or wireless phone, to accurately determine energy usage drawn from the power supply unit under rapidly dynamic circumstances. A current sense signal of a power line from the power supply unit is digitized. The digitized current sense is added to an accumulator at a rate that is approximately proportional to a voltage of the power line from the power supply unit. The accumulator is then outputted and scaled to units relevant to energy measurements. The energy measurement is used to estimate remaining battery life. Triggering the digitization of the current sense signal may be by use of a pulse generation circuit, or by use of an overflow indicator of an accumulator for a digitized voltage sense signal. Other examples are described and claimed.
