Method and apparatus for reducing bus traffic of a texture decoding module in a video decoder
Abstract:
Techniques for reducing bus traffic during texture decoding of a video bitstream are provided. In one configuration, a wireless communication device (e.g., cellular phone, etc.) comprises a processor configured to execute instructions operative to decode and separate in a bitstream macroblock (MB) information and residual packet data. The residual packet data is used to generate codec-independent non-zero MB-packets having a universal order that is codec independent. The codec-independent non-zero MB-packets and MB information are then used for reconstructing pixels of a respective frame of the video bitstream.
