Data storage

A method performed by a processor comprising tensor processing circuitry, the method comprising:

• obtaining mapping data indicative of at least one mapping parameter for a plurality of mapping blocks of a multi-dimensional tensor to be mapped, wherein the at least one mapping parameter is for mapping corresponding elements of each mapping block to the same co-ordinate in at least one selected dimension of the multi-dimensional tensor, such that each mapping block corresponds to the same set of co-ordinates in the at least one selected dimension;
• determining, based on the mapping data, a co-ordinate of an element of a block of the multi-dimensional tensor, a mapping block of the plurality of mapping blocks comprising the element;
• determining, based on the co-ordinate, a physical address in a memory corresponding to the co-ordinate;
• and
• accessing the memory at the physical address in a process comprising an interaction between the block of the multi-dimensional tensor and the memory.

A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon which, when executed by at least one processor comprising tensor processing circuitry, are arranged to cause the at least one processor to:

• obtain mapping data indicative of at least one mapping parameter for a plurality of mapping blocks of a multi-dimensional tensor to be mapped, wherein the at least one mapping parameter is for mapping corresponding elements of each mapping block to the same co-ordinate in at least one selected dimension of the multi-dimensional tensor, such that each mapping block corresponds to the same set of co-ordinates in the at least one selected dimension;
• determine, based on the mapping data, a co-ordinate of an element of a block of the multi-dimensional tensor, a mapping block of the plurality of mapping blocks comprising the element;
• determine, based on the co-ordinate, a physical address in a memory corresponding to the co-ordinate;
• and
• access the memory at the physical address in a process comprising an interaction between the block of the multi-dimensional tensor and the memory.
