Assignee: DEEPX CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A neural processing unit (NPU) for decoding video and/or feature map, the NPU comprising:
a first circuitry provided for at least one processing element (PE) to perform an inference using an artificial neural network, the at least one PE is configured to receive and decode data included in a bitstream,
wherein the data included in the bitstream comprises:
data of a base layer, or
the data of the base layer and data of at least one enhancement layer,

wherein the data of the base layer included in the bitstream includes a first feature map, and the data of the at least one enhancement layer included in the bitstream includes a second feature map,
wherein the bitstream is received in unit of one frame,
wherein a number of enhancement layers to be included in the frame is determined based on at least one of a transmission channel and a machine analysis task, and
wherein feedback information on the number of enhancement layers is transmitted to an encoding apparatus.
