Abstract
Disclosed herein are a High-Bandwidth Memory (HBM)-based holography processing apparatus and method. The HBM-based holography processing apparatus includes a holography row processing unit configured to receive image data and output row data of complex numbers obtained by performing a Fast Fourier Transform (FFT) on the image data, a HBM configured to store the output row data as data for each color and for each depth, and a holography column processing unit configured to read the stored row data using a column address and perform FFT processing on the read row data.

A High-Bandwidth Memory (HBM)-based holography processing apparatus, comprising:
- a holography row processing unit configured to receive image data and output row data of complex numbers obtained by performing a Fast Fourier Transform (FFT) on the image data;
- a HBM configured to store the output row data as data for each color and for each depth;
- and
- a holography column processing unit configured to read the stored row data using a column address and perform FFT processing on the read row data,
- wherein the HBM is configured to allow writing to one of at least two channels for each color or depth while reading from a remaining channel.
