Original Abstract Submitted

embodiments of the present disclosure relate to a texture unit circuit in a neural processor circuit. the neural processor circuit includes a tensor access operation circuit with the texture unit circuit, a data processor circuit, and at least one neural engine circuit. the texture unit circuit fetches a source tensor from a system memory by referencing an index tensor in the system memory representing indexing information into the source tensor. the data processor circuit stores an output version of the source tensor obtained from the tensor access operation circuit and sends the output version of the source tensor as multiple of units of input data to the at least one neural engine circuit. the at least one neural engine circuit performs at least convolution operations on the units of input data and at least one kernel to generate output data.
