STORING MISALIGNED REFERENCE PIXEL TILES

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.
