Claim 18:
19. An electronic device, comprising:
a system memory; and
a neural processor circuit including at least one neural engine circuit, a data processor circuit and a tensor access operation circuit,
the tensor access operation circuit coupled to the data processor circuit and the system memory, the tensor access operation circuit configured to read a source tensor from the system memory by referencing an index tensor in the system memory representing indexing information into the source tensor,
the data processor circuit coupled to the tensor access operation circuit, the data processor circuit configured to:
store an output version of the source tensor obtained from the tensor access operation circuit, and
send the output version of the source tensor as a plurality of units of input data,

the at least one neural engine circuit coupled to the data processor circuit, the at least one neural engine circuit configured to:
receive the plurality of units of input data from the data processor circuit, and
perform at least convolution operations on the plurality of units of input data and at least one kernel to generate output data.
