FFT PARALLEL PROCESSING METHOD, DATA PROCESSING METHOD AND HOLOGRAM RESTORATION APPARATUS

摘要

An FFT parallel processing method, a data processing method applied the same, and a hologram restoration apparatus are provided. The data processing method according to an embodiment of the present invention generates partition data by dividing input data; executes FFT calculation with the partition data; executes the changed FFT calculation with the partition data; and outputs the changed data by composing calculation results. Therefore, The method may execute FFT by dividing the data and may rapidly execute the FFT calculation. The method may restore massive hologram data and may prevent communication delay and image disconnection by rapidly executing the FFT calculation. [Reference numerals] (AA) Parallel 2D-FFT
