Abstract: This disclosure provides systems, methods, and devices for image signal processing that support efficient cache usage in an image processing system. In a first aspect, a method of image processing includes storing, by an image processor, a first portion of a first stripe of a first frame in a cache, the first portion of the first stripe overlapping a second portion of a second stripe of the first frame, reading, by the image processor, a third portion of the second stripe from a memory, reading, by the image processor, the first portion of the first stripe from the cache, and processing, by the image processor, the second stripe using the first portion of the first stripe and the third portion of the second stripe. Other aspects and features are also claimed and described.

Abstract: Video decoding systems and techniques are described. The decoder applies a deblocking (DB) filter to the plurality of sub-blocks of a block of video data to generate a DB-filtered plurality of sub-blocks. The decoder applies the DB filter to one or more lines (e.g., columns) of pixels in an additional sub-block of the block to generate a DB-filtered portion of the additional sub-block. The one or more lines of pixels in the additional sub-block are filtered without filtering an entirety of the additional sub-block using the DB filter. The additional sub-block is adjacent to at least one of the plurality of sub-blocks. The decoder applies a constrained directional enhancement filter (CDEF) to the DB-filtered plurality of sub-blocks and the DB-filtered portion of the additional sub-block to generate a CDEF-filtered plurality of sub-blocks.
