Transpose of image data between a linear and a Y-tiled storage format

At least one non-transitory machine readable medium comprising a plurality of instructions that in response to being executed on a computing device, cause the computing device to:

• reading image data from a source memory, wherein the source memory has a source storage format, wherein the reading of the source memory is in a pattern adapted for the source memory;
• transposing the image data from the source storage format to a destination storage format different from the source storage format, wherein one of the source storage format and the destination storage format have a linear-type storage format and the other of the source storage format and the destination storage format have a Y-tiled-type storage format;
• and
• writing image data into a destination memory, wherein the destination memory has the destination storage format, wherein the writing of the destination memory is in a pattern adapted for the destination memory;
• wherein during the series of reading-transposing-writing operations on the image all of the space associated with a plurality of cache line source accesses is utilized without redundant accesses during the reading of image from the source memory and all of the space associated with a plurality of cache line destination accesses is utilized without redundant accesses during the writing of image data into the destination memory.

An apparatus, comprising:

• a processor configured to:
• read image data from a source memory, wherein the source memory has a source storage format, wherein the read of the source memory is in a pattern adapted for the source memory;
• transpose the image data from the source storage format to a destination storage format different from the source storage format, wherein one of the source storage format and the destination storage format have a linear-type storage format and the other of the source storage format and the destination storage format have a Y-tiled-type storage format;
• and
• write image data into a destination memory, wherein the destination memory has the destination storage format, wherein the write of the destination memory is in a pattern adapted for the destination memory;
• wherein during the series of reading-transposing-write operations on the image all of the space associated with a plurality of cache line source accesses is utilized without redundant accesses during the read of image from the source memory and all of the space associated with a plurality of cache line destination accesses is utilized without redundant accesses during the write of image data into the destination memory.

A system comprising:

• a display;
• a processor, wherein the processor is communicatively coupled to the display, wherein the processor configured to:
• read image data from a source memory, wherein the source memory has a source storage format, wherein the read of the source memory is in a pattern adapted for the source memory;
• transpose the image data from the source storage format to a destination storage format different from the source storage format, wherein one of the source storage format and the destination storage format have a linear-type storage format and the other of the source storage format and the destination storage format have a Y-tiled-type storage format;
• and
• write image data into a destination memory, wherein the destination memory has the destination storage format, wherein the write of the destination memory is in a pattern adapted for the destination memory;
• wherein during the series of reading-transposing-write operations on the image all of the space associated with a plurality of cache line source accesses is utilized without redundant accesses during the read of image from the source memory and all of the space associated with a plurality of cache line destination accesses is utilized without redundant accesses during the write of image data into the destination memory.
