Patent number: 11561797Abstract: An electronic device that includes a decompression engine that includes N decoders and a decompressor decompresses compressed input data that includes N streams of data. Upon receiving a command to decompress compressed input data, the decompression engine causes each of the N decoders to decode a respective one of the N streams from the compressed input data separately and substantially in parallel with others of the N decoders. Each decoder outputs a stream of decoded data of a respective type for generating commands associated with a compression standard for decompressing the compressed input data. The decompressor next generates, from the streams of decoded data output by the N decoders, commands for decompressing the data using the compression standard to recreate the original data. The decompressor next executes the commands to recreate the original data and stores the original data in a memory or provides the original data to another entity.Type: GrantFiled: August 19, 2019Date of Patent: January 24, 2023Assignee: ATI Technologies ULCInventor: Vinay Patel

Patent number: 11562459Abstract: A graphics pipeline includes a cache having cache lines that are configured to store data used to process frames in a graphics pipeline. The graphics pipeline is implemented using a processor that processes frames for the graphics pipeline using data stored in the cache. The processor processes a first frame and writes back a dirty cache line from the cache to a memory concurrently with processing of the first frame. The dirty cache line is retained in the cache and marked as clean subsequent to being written back to the memory. In some cases, the processor generates a hint that indicates a priority for writing back the dirty cache line based on a read command occupancy at a system memory controller.Type: GrantFiled: December 21, 2020Date of Patent: January 24, 2023Assignees: ADVANCED MICRO DEVICES, INC., ATI TECHNOLOGIES ULCInventors: Noor Mohammed Saleem Bijapur, Ashish Khandelwal, Laurent Lefebvre, Anirudh R.

Patent number: 11551632Abstract: A graphics processing unit (GPU) of a processing system transmits pixel data for a frame to a display in a compressed burst, so that the pixel data is communicated at a rate that is higher than the rate at which the display scans out the pixel data to refresh the frame at a display panel. By transmitting pixel data for the frame in a compressed burst, the GPU shortens the time spent transmitting the pixel data and extends the time before the next frame of pixel data is to be transmitted. During the extended time before the next frame of pixel data is to be transmitted, the GPU saves power by placing portions of the processing system in a reduced power mode.Type: GrantFiled: September 23, 2020Date of Patent: January 10, 2023Assignee: ATI TECHNOLOGIES ULCInventors: Syed Athar Hussain, Anthony W L Koo, David I.

Patent number: 11551398Abstract: Systems, apparatuses, and methods for implementing light volume rendering techniques are disclosed. A processor is coupled to a memory. A processor renders the geometry of a scene into a geometry buffer. For a given light source in the scene, the processor initiates two shader pipeline passes to determine which pixels in the geometry buffer to light. On the first pass, the processor renders a front-side of a light volume corresponding to the light source. Any pixels of the geometry buffer which are in front of the front-side of the light volume are marked as pixels to be discarded. Then, during the second pass, only those pixels which were not marked to be discarded are sent to the pixel shader. This approach helps to reduce the overhead involved in applying a lighting effect to the scene by reducing the amount of work performed by the pixel shader.Type: GrantFiled: August 31, 2020Date of Patent: January 10, 2023Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Mika Tuomi, Miikka Petteri Kangasluoma, Jan Henrik Achrenius, Laurent Lefebvre
