Abstract: A graphics accelerator device offloads the workload of a graphics processing unit (GPU) by performing image composition and other specialized functions. The graphics accelerator device includes a rasterization module to rasterize a set of primitives to a set of pixels and generate information of the set of pixels. The graphics accelerator device also includes intra-process module to retrieve pixel values from a memory according to the information received from the rasterization module, perform mathematical calculations on the pixel values, and generate one or more processed image layers. The graphics accelerator device further includes an inter-process module to composite the one or more processed image layers received from the intra-process module with other image layers retrieved from the memory, and output a composited image to a display.
