Claim 0:
1. A neural processing unit comprising:
an internal memory including a plurality of memory units;
a controller configured to control read and write operations of data of at least one of an input feature map domain, a weight domain, and an output feature map domain with respect to each of the plurality of memory units based on an operation schedule in a machine code in which a plurality of operation steps of an artificial neural network model are set
a direct memory access (DMA) configured to read data from a main memory and to write input feature map data and weight data to the internal memory; and
an artificial intelligence (AI) calculation unit configured to receive and operate the input feature map data and the weight data from the internal memory to generate output feature map data
wherein the internal memory further includes a weight multiplexer, an input feature map multiplexer, and an output feature map demultiplexer, respectively connected to each of the plurality of memory units.
