    摘要: Methods and apparatus relating to a current change mitigation policy for limiting voltage droop in graphics logic are described. In an embodiment, logic inserts one or more bubbles in one or more Execution Unit (EU) logic pipelines or one or more sampler logic pipelines of a processor. The bubbles at least temporarily reduce execution of operations in one or more subsystems of the processor based at least partially on a comparison of a first value and one or more clamping threshold values. The first value is determined based at least partially on a summation of products of one or more event counts and dynamic capacitance weights for one or more subsystems of the processor. Other embodiments are also disclosed and claimed.

    摘要: Methods and apparatus relating to clamping or reducing of dynamic capacitance for graphics logic are described. In one embodiment, utilization values for a plurality of subsystems of a graphics logic are determined and a first capacitance value is in turn determined based on (e.g., a sum of products of) the determined utilization values (e.g., and one or more capacitance weight values). A second capacitance value (e.g., corresponding to a maximum dynamic capacitance or Cdyn_max corresponding to the graphics logic) is modified based on (e.g., a comparison of the first capacitance value and a (e.g., threshold) capacitance value. Other embodiments are also disclosed and claimed.
