Latest Patents

One of his latest patents is for a Graphics Accelerator. This 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 that rasterizes a set of primitives to a set of pixels and generates information about the set of pixels. Additionally, it features an intra-process module that retrieves pixel values from memory according to the information received from the rasterization module, performs mathematical calculations on the pixel values, and generates one or more processed image layers. Furthermore, the device includes an inter-process module that composites the processed image layers with other image layers retrieved from memory, ultimately outputting a composited image to a display.

Another significant patent is for a graphic processing system and method thereof. This system includes a collector, a plurality of slots, a scheduler, an arbiter, and at least one arithmetic logic unit (ALU). The collector groups a plurality of work items into elementary wavefronts, with each wavefront comprising work items configured to execute the same kernel code. The scheduler allocates the elementary wavefronts to the slots, allowing two or more elementary wavefronts to exist at one slot to form one of several macro wavefronts. The arbiter selects one of the macro wavefronts, while the ALU executes work items of at least one elementary wavefront of the selected macro wavefront and outputs the results of the execution.
