US 2026/0087337 A1 · NEURAL PROCESSING UNIT AND METHOD FOR MULTI-STAGE VIDEO QUALITY IMPROVEMENT

Abstract

A neural processing unit (NPU) includes an internal memory storing information on combinations of a plurality of artificial neural network (ANN) models, the plurality of ANN models including first and second ANN models; a plurality of processing elements (PEs) to process first operations and second operations of the plurality of ANN models in sequence or in parallel, the plurality of PEs including first and second groups of PEs; and a scheduler to allocate to the first group of PEs a part of the first operations for the first ANN model and to allocate to the second group of PEs a part of the second operations for the second ANN model, based on an instruction related to information on an operation sequence of the plurality of ANN models or further based on ANN data locality information. The first and second operations may be performed in parallel or in a time division.

Dependent claims

A method for improving video quality using a neural processing unit (NPU), the method comprising:

receiving, by the NPU, a video stream;
decompressing or decoding, by a first artificial neural network (ANN) model executed on the NPU, the received video stream;
performing, by a second ANN model executed on the NPU, a video preprocessing on the decompressed or decoded video stream;
and
applying, by a third ANN model executed on the NPU, a super-resolution process to the preprocessed video stream to generate an enhanced video stream.
