4.1.3 miniDSP Applications
The TLV320AIC3254 features two miniDSP cores, one for the ADC and another for the DAC.
Currently, the AIC3254 CS has two DAC miniDSP applications: Equalizers and Spectrum Analyzer. Visit
the TLV320AIC3254EVM-K product folder for updates and availability on new miniDSP applications.
See the miniDSP section in the data sheet (SLAS549) for information on how to develop custom miniDSP
algorithms.
4.1.3.1 Equalizers
The Equalizers miniDSP application features 20 cascaded biquad filters per DAC channel (Figure 14).
Each of the 40 20-Band EQ sliders modify its corresponding biquad filter in the cascade as a function of
gain. Each Master slider controls the digital volume control of the TLV320AIC3254. All sliders can be set
to track the opposing channel slider movement by turning on the Lock L+R switch. Preset configurations
are available at the red selection box below the graphic equalizer. A frequency slider movement changes
any preset to Custom.
