CONFIG_CMSIS_DSP_TRANSFORM

Transform Functions

Type: bool

Help

This option enables the Transform Functions, which support the
following transformations:

* Real Fast Fourier Transform (RFFT)
* Complex Fast Fourier Transform (CFFT)
* Type IV Discrete Cosine Transform (DCT4)

Direct dependencies

CMSIS_DSP

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.

Symbols selected by this symbol

CMSIS_DSP_TABLES

Symbols implied by this symbol

CMSIS_DSP_TABLES_ALL_FFT

Kconfig definition
