Optimizing an operation on tensors with respect to a processing device

A method of computer implementation, comprising:

• determining, based on a size of a target tensor, a target window size for performing a target operation associated with the target tensor on a processing device;
• determining at least one data block based on the target window size and the target tensor, a set of elements comprised in the at least one data block covering at least the target tensor;
• and
• for each data block in the at least one data block, performing at least one of a plurality of predetermined tasks corresponding to the target operation and the target window size based on a position of each element of the data block in the target tensor, the plurality of predetermined tasks being precompiled for the processing device to perform the target operation on a tensor with the target window size.

• a processing unit;
• and
• a memory coupled to the processing unit and comprising instructions stored thereon, the instructions, when executed by the processing unit, causing the device to perform acts comprising:
• determining, based on a size of a target tensor, a target window size for performing a target operation associated with the target tensor on a processing device;
• determining at least one data block based on the target window size and the target tensor, a set of elements comprised in the at least one data block covering at least the target tensor;
• and
• for each data block in the at least one data block, performing at least one of a plurality of predetermined tasks corresponding to the target operation and the target window size based on a position of each element of the data block in the target tensor, the plurality of predetermined tasks being precompiled for the processing device to perform the target operation on a tensor with the target window size.
