Title:
POOLING DEVICE FOR DEEP LEARNING ACCELERATOR
Document Type and Number:
WIPO Patent Application WO/2023/080291
Kind Code:
A1
Abstract:
A pooling device for a deep learning accelerator is provided. A pooling apparatus according to an embodiment of the present invention comprises: a line memory in which lines constituting input data are sequentially stored one by one; a first comparator that selects a specific value by comparing data in which a first window is located, from among data currently stored in the line memory; a memory in which a first previous specific value being the specific value previously selected by the first comparator is stored; and a third comparator that selects a specific value by comparing the data in which the first window is located, from among the data currently stored in the line memory with the first previous specific value applied from the memory. Accordingly, it is possible to minimize input and output of an internal memory in a deep learning accelerator, thereby reducing calculation time and reducing the amount of hardware resources used to thus enable low-power operation.
