Indirectly accessing sample data to perform multi-convolution operations in a parallel processing system

A non-transitory, computer-readable storage medium including instructions that, when executed by a processor, cause the processor to perform a multi-convolution operation, by performing the steps of:

• selecting a first start address based on a first destination address included in a first image tile that is stored in a first memory and includes a plurality of rows associated with image data included in an image batch;
• identifying a first offset in an offset sequence based on the first destination address, wherein the offset sequence corresponds to a pattern of source addresses of the image data included in the image batch and specifies an offset for each row included in the first image tile;
• computing a first source address included in the image batch based on the first start address and the first offset;
• copying data from the first source address to the first destination address;
• and
• after copying the data, performing one or more matrix multiplication operations between the first image tile and a first filter tile.

A system configured to perform a multi-convolution operation, the system comprising:

• a first memory;
• a second memory;
• and
• a convolution engine coupled to both the first memory and the second memory, and configured to:
• identify a first offset included in an offset sequence based on a first destination address included in a first image tile that is stored in the first memory and includes a plurality of rows associated with image data included in an image batch that is stored in the second memory, wherein the offset sequence corresponds to a pattern of source addresses included in the image batch and specifies an offset for each row included in the first image tile;
• compute a first source address included in an image batch based on the first offset;
• copy data from the first source address to the first destination address;
• and
• after copying the data, perform one or more matrix multiplication operations between the first image tile and a first filter tile.
