System and method for compacting compressed graphics streams for transfer between GPUs

A method, comprising:

• parsing first metadata associated with a first compressed graphics stream comprising a plurality of memory blocks of graphics data, wherein the first metadata indicates a first compression method for the first compressed graphics stream;
• compacting the first compressed graphics stream, wherein compacting comprises removing padding for data alignment from the memory blocks;
• interleaving the first metadata with the compacted first compressed graphics stream;
• transmitting the compacted first compressed graphics stream and the interleaved first metadata from a first graphics processing unit (GPU) to a second GPU;
• and
• decompacting, at the second GPU, the first compacted compressed stream of graphics data, wherein decompacting comprises reinserting padding for data alignment into the plurality of memory blocks.

A device, comprising:

• a plurality of graphics processing units (GPUs), each GPU comprising:
• a compacting engine configured to:
• parse first metadata from a first compressed stream of graphics data comprising a plurality of memory blocks of graphics data, wherein the first metadata indicates a first compression method for the first compressed graphics stream;
• compact the first compressed graphics stream, wherein compacting comprises removing padding for data alignment from the memory blocks;
• interleave the first metadata with the compacted first compressed graphics stream;
• and
• transmit the compacted first compressed graphics stream and the interleaved first metadata from a first GPU of the plurality of GPUs to a second GPU of the plurality of GPUs;
• and
• a decompacting engine configured to:
• receive a compacted second compressed graphics stream and second metadata, wherein the second metadata indicates a second compression method for the compacted second compressed graphics stream;
• and
• decompact the compacted second compressed graphics stream, wherein decompacting comprises reinserting padding for data alignment into the plurality of memory blocks.
