Hybrid convolution operation

A method of performing convolution, comprising:

• retrieving, at one or more processors, a first block of data and at least a portion of a second block of data from a memory, the data corresponding to an array of values arranged along at least a first dimension and a second dimension;
• performing a first hybrid convolution operation that applies a filter across the first block and at least the portion of the second block to generate output data,
• wherein the output data includes a first accumulated block and at least a portion of a second accumulated block;
• and
• storing the first accumulated block as first output data, wherein the portion of the second block is adjacent to the first block along the first dimension and the portion of the second accumulated block is adjacent to the first accumulated block along the second dimension.

A computer-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to:

• retrieve a first block of data and at least a portion of a second block of data from a memory, the data corresponding to an array of values arranged along at least a first dimension and a second dimension;
• perform a first hybrid convolution operation that applies a filter across the first block and at least the portion of the second block to generate output data,
• wherein the output data includes a first accumulated block and at least a portion of a second accumulated block;
• and
• store the first accumulated block as first output data, wherein the portion of the second block is adjacent to the first block along the first dimension and the portion of the second accumulated block is adjacent to the first accumulated block along the second dimension.

An apparatus comprising:

• means for retrieving a first block of data and at least a portion of a second block of data, the data corresponding to an array of values arranged along at least a first dimension and a second dimension;
• means for performing a hybrid convolution operation that applies a filter across the first block and at least the portion of the second block to generate output data,
• wherein the output data includes a first accumulated block and at least a portion of a second accumulated block;
• and
• means for storing the first accumulated block as first output data, wherein the portion of the second block is adjacent to the first block along the first dimension and the portion of the second accumulated block is adjacent to the first accumulated block along the second dimension.
