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.

Graphics Accelerator

A graphic processing system and a method of graphic processing are provided. The graphic processing system has a collector, a plurality of slots, a scheduler, an arbiter and at least an arithmetic logic unit (ALU). The collector is configured to group a plurality of workitems into elementary wavefronts. Each of the elementary wavefronts comprises workitems configured to execute the same kernel code. The scheduler is configured to allocate the elementary wavefronts to the slots. Two or more of the elementary wavefronts exist at one slot to form one of a plurality of macro wavefronts. The arbiter is configured to select one of the macro wavefronts. The ALU is configured to execute workitems of at least an elementary wavefront of the selected macro wavefront and output results of execution of the workitems.
