US 2026/0087336 A1 · NEURAL PROCESSING ARCHITECTURE IMPLEMENTING AN AI-ISP FOR ENHANCED OBJECT RECOGNITION

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

An edge device, comprising:

an image sensor configured to acquire image data;
a plurality of neural processing units (NPUs) including at least a first NPU and a second NPU;
and
a control central processing unit (CPU) configured to:
execute, on the first NPU, a first artificial neural network (ANN) model to improve a quality of the image data, thereby generating enhanced image data;
and
execute, on the second NPU, a second ANN model to perform an object recognition task based on the enhanced image data generated by the first NPU.
