Abstract: Systems and techniques are provided for caching misaligned pixel tiles. A method includes determining a first codec region including a first region of a frame; determining whether pixels of a first version of a pixel tile were stored in a cache while coding blocks from a second codec region, the pixel tile corresponding to a location within the frame; based on whether the pixels were stored in the cache, determining whether to read the first version of the pixel tile from the cache or retrieve a second version of the pixel tile from a memory device, the second version of the pixel tile including pixels from the first codec region that are not in the first version of the pixel tile; and coding a block based on the first version of the pixel tile read from the cache or second version of the pixel tile retrieved from the memory device.

Abstract: An apparatus configured to decode video data includes a shared memory and one or more processors configured to execute a plurality of video decoding cores. At least one of the plurality of video decoding cores in communication with the shared memory, and each of plurality of video decoding cores are configured to track completion of decoding samples of one or more regions of a frame of video data, write information to the shared memory, the information indicative of the completion of decoding the samples of the one or more regions of the frame of video data, read, prior to decoding a subsequent region of the frame of video data, the information in the shared memory, and determine whether to decode the subsequent region of the frame of video data based on the information.

Abstract: An example apparatus includes a first frame buffer configured to store video data; a second frame buffer configured to store video data; and one or more processors configured to: reconstruct samples of a first block of a current picture of video data; store, in parallel, a compressed version of the samples of the first block of video data in the first frame buffer and an uncompressed version of the samples of the first block of video data in the second frame buffer; and responsive to determining to reconstruct a second block of the current picture of video data using intra block copy: obtain, from the second frame buffer, samples of a predictor block located in the current picture of video data, the predictor block at least partially overlapping the first block of video data; and predict, based on the obtained samples of the predictor block, samples of the second block.
