Abstract:
1. A power-gating control method for a graphics processing unit having a unified shader unit, which comprises a plurality of shaders, comprising: rendering a plurality of previous frames via first active shaders of the plurality of shaders; calculating a number of the first active shaders required for rendering each of the plurality of previous frames, and respective frame rate of each of the plurality of previous frames; determining a number of second active shaders of the plurality of shaders used for rendering a next frame immediately following the previous frames based on the calculated number of the first active shaders required for rendering each of the plurality of previous frame and the calculated frame rate of each previous frame; and activating corresponding shaders of the plurality of shaders through one or more power-gating control elements according to the determined number of the second active shaders used for rendering the next frame immediately following the previous frames.
