US 12,223,682 B2 · Variable width interleaved coding for graphics processing

Abstract

Variable width interleaved coding for graphics processing is described. An example of an apparatus includes one or more processors including a graphic processor; and memory for storage of data including data for graphics processing, wherein the graphics processor includes an encoder pipeline to provide variable width interleaved coding and a decoder pipeline to decode the variable width interleaved coding, and wherein the encoder pipeline is to receive a plurality of bitstreams from workgroups; perform parallel entropy encoding on the bitstreams to generate a plurality of encoded bitstreams for each of the workgroups; perform variable interleaving of the bitstreams for each workgroup based at least in part on data requirements for decoding received from the decoder pipeline; and compact outputs for each of the workgroups into a contiguous stream of interleaved data.

Dependent claims

An apparatus comprising:

one or more processors including a graphic processor;
and
memory for storage of data including data for graphics processing;
wherein the graphics processor includes an encoder pipeline to provide variable width interleaved coding and a decoder pipeline to decode the variable width interleaved coding, and wherein the encoder pipeline is to:
receive a plurality of bitstreams from a plurality of workgroups;
perform parallel entropy encoding on the bitstreams to generate a plurality of encoded bitstreams for each of the workgroups;
perform variable interleaving of the bitstreams for each workgroup of the plurality of workgroups, wherein a number of data elements that are interleaved for each workgroup in each of a plurality of iterations is based at least in part on current data requirements for decoding for each workgroup received from the decoder pipeline;
and
compact interleaved bitstream outputs for each of the plurality of workgroups into a contiguous stream of interleaved data.

6 more elements

One or more non-transitory computer-readable storage mediums having stored thereon executable computer program instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

receiving a plurality of bitstreams from a plurality of workgroups at an encoder pipeline;
performing parallel entropy encoding on the bitstreams to generate a plurality of encoded bitstreams for each of the workgroups;
performing variable interleaving of the bitstreams for each workgroup of the plurality of workgroups, wherein a number of data elements that are interleaved for each workgroup in each of a plurality of iterations is based at least in part on current data requirements for decoding received from a decoder pipeline;
and
compacting interleaved bitstream outputs for each of the plurality of workgroups into a contiguous stream of interleaved data.
