- CONFIG_INTEL_DMIC_FIR_LOW_MEMORY¶
Small set
Type: bool
Help¶
This option is used to minimize driver footprint but
preserve support for 48 kHz and 16 kHz sample rates
at typical 2.4 MHz microphone clock rate. The option
enables decimation factors 2 and 6.
Direct dependencies¶
<choice: FIR decimation coefficients set>
(Includes any dependencies from ifs and menus.)
