CONFIG_CMSIS_DSP_FILTERING¶
Filtering Functions
Type: bool
Help¶
This option enables the Filtering Functions, which support the
following operations:
* Convolution
* Partial Convolution
* Correlation
* Levinson-Durbin Algorithm
The following filter types are supported:
* FIR (finite impulse response) Filter
* FIR Lattice Filter
* FIR Sparse Filter
* FIR Filter with Decimator
* FIR Filter with Interpolator
* IIR (infinite impulse response) Lattice Filter
* Biquad Cascade IIR Filter, Direct Form I Structure
* Biquad Cascade IIR Filter, Direct Form II Transposed Structure
* High Precision Q31 Biquad Cascade Filter
* LMS (least mean square) Filter
* Normalized LMS Filter
Direct dependencies¶
(Includes any dependencies from ifs and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
