Abstract
A neural processing unit (NPU) for decoding video and/or feature map may incluide at least one processing element (PE) for an artificial neural network (ANN), the at least one PE to receive and decode a bitstream. The bitstream is received in units of frames, and one frame includes a weight for an ANN model, data of a base layer, and data of a plurality of enhancement layers. An NPU for encoding video and/or feature map may include at least one processing element (PE) for an artificial neural network (ANN), the at least one PE to encode an input video or feature map and to transmit the encoded input video or feature map as a bitstream. The at least one PE transmits the bitstream in units of frames, and one frame includes a weight for an ANN model, data of a base layer, and data of a plurality of enhancement layers.
