Video processing architecture

摘要

A method for video processing may include receiving video data units, and compressing the video data units to generate compressed video data units that have a variable size. The method may also include storing the compressed video data units contiguously in a memory in memory segments that have a fixed size, where the size of at least one of the compressed video data units is indivisible by the fixed size of the memory segments, and where a portion of the indivisible compressed video data unit is stored with a portion of another compressed video data unit in one of the memory segments. The method may also include determining data storage information associated with the compressed video data units, and storing the data storage information in the memory. A system may have a video processing architecture designed to support the method.

主权项

1. A method comprising:
receiving, at a video processing unit of a video processing apparatus, video data units; compressing the video data units to generate compressed video data units that have a variable size; storing the compressed video data units contiguously in a memory in memory segments that have a fixed size, wherein:
the size of a first compressed video data unit of the compressed video data units is indivisible by the fixed size of the memory segments;a first portion of the first compressed video data unit is stored in a first memory segment of the memory segments; anda second portion of the first compressed video data unit is stored in a second memory segment of the memory segments with at least a portion of a second compressed video data unit of the compressed video data units; determining data storage information associated with the first compressed video data unit that comprises a number of memory segments used to store the first compressed video data unit; and storing the data storage information in the memory.
