Classification: CPC G | IPC G

Claim 14:
15. A system comprising:
a main memory configured to store at least a portion of data of at least one artificial neural network model; and
a neural processing unit comprising:
a variable memory including a plurality of memory unit and at least one selectors connected to each of the plurality of memory unit and configured to select each of the plurality of memory units based on the at least one artificial neural network model, the variable memory configured to divide the portion of the data of the at least one artificial neural network model into a feature map and a weight and to selectively store the feature map and the weight in a specific unit of the plurality of memory units;

a direct memory access (DMA) circuit configured to control a memory operation between the main memory and the variable memory; and
an AI calculation unit configured to receive the feature map and the weight from the variable memory and to process an artificial neural network inference operation.
