Method for performing acceleration operation on feature data, medium, and device

Abstract

A method includes: determining, from input feature data, an input point corresponding to an output point in to-be-calculated output feature data; determining a target region tag that matches the input point based on a position parameter of the input point; determining existence information on a target feature value group mapped by the target region tag in an on-chip buffer, where a feature value group mapped by any region tag includes feature values of a plurality of points in the input feature data that match the region tag; determining a target memory adapted to the existence information from the on-chip buffer and an on-chip main memory that stores the input feature data; calculating a feature value of the output point based on a feature value of the input point in the target memory; and calculating the output feature data based on the feature value of the output point.
