To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Embedded Coder Support Package for Qualcomm Hexagon Processors / Hexagon / IPCV

Description

The HVX FFT2 block computes the two-dimensional (2-D) fast Fourier transform (FFT) of a real-valued input matrix using the Qualcomm^® Hexagon^® Vector eXtensions (HVX) library.

The block supports simulation and generates optimized code for Qualcomm DSPs using CRL-based replacements. Use this block to perform matrix-based frequency-domain computations in image processing and similar workflows.
