Reduce Bandwidth While Reading in Textures During Frame Composition
Smart Composition helps reduce bandwidth while reading in textures during frame composition. By analyzing frames prior to final frame composition, Smart Composition determines if any reason exists to render a given portion of the frame or whether the previously rendered and composited portion can be reused. If that portion of the frame can be reused then it is not read from memory again or recomposited, thereby saving additional computational effort. Smart Composition can reduce standard Android™ User Interface texture read bandwidth by better than 50 percent.
Reducing bandwidth can lead to important power savings, depending on the design of your SoC. Talk to an Arm expert about what solutions will help reduce overall SoC power.
