HVX IFFT2 block

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 IFFT2 block computes the inverse two-dimensional fast Fourier transform (IFFT) 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 reconstruct spatial-domain data from frequency-domain representations in image processing and similar workflows.

Ports

Input

in — Input signal

complex 2-D square matrix

Input signal, specified as a complex 2-D square matrix. The dimension of the square matrix must be a power of two and greater than or equal to 64.

Data Types: single
Complex Number Support: Yes

Output

out — IFFT output

real 2-D matrix

IFFT output, returned as a real-valued 2-D matrix.

Data Types: single

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
