A scalable in-memory image processing system and method based on WHT

Abstract

The application belongs to the technical field of signal analysis and signal processing, and specifically discloses an extensible in-memory image processing system and method based on WHT. According to the application, a first input processing module is used to split an image into a plurality of first data groups in a first direction, and output corresponding first voltage pulse signals. An operation unit is used to process the first voltage pulse signals corresponding to each first data group by using a memristor array to map a matrix corresponding to a WHT operator, and obtain a plurality of first current pulse signals corresponding thereto. An output processing module is used to convert the first current pulse signals output by the operation unit into corresponding second data groups, recombine the plurality of second data groups in a second direction, and obtain final output data. According to the application, a fixed-size memristor array can be used to realize WHT operation of any scale, thereby reducing the operation amount of the system while maintaining low power consumption.
