Other Parts Discussed in Thread: TLV320AIC3120, TLV320AIC3262

Hello,

Is the DSP embedded in TLV320AIC3120 has enough power to process noise and echo cancellation using?

Hello Diego,

Thanks for your answer, it seems wiki link is missing…

Am I right?

Hello,

Regarding the link, AEC is not supported by miniDSP but I am quoting http://www.ti.com/lit/ug/slau309/slau309.pdf :

“

The TLV320AIC3262 features two fully programmable miniDSP cores. The first miniDSP core is tightly

coupled to the ADC, the second miniDSP core is tightly coupled to the DAC. The algorithms for the

miniDSP must be loaded into the device after power up. The miniDSPs have direct access to the digital

stereo audio stream on the ADC and on the DAC side, offering the possibility for advanced, very-low

group delay DSP algorithms. Each miniDSP can run up to 1145 instructions on every audio sample at a

48kHz sample rate. The two cores can run fully synchronized and can exchange data. The

TLV320AIC3262 features the ability to process a multitude of algorithms simultaneously. For example, the

miniDSPs enable simultaneous noise cancellation, acoustic echo cancellation, sidetone, equalization

filtering, dynamic range compression, conversation recording, user-interface sound mixing, and other

voice enhancement processing at voice-band sampling rates (e.g. 8kHz) and high-defintion voice sampling

rates (e.g. 16kHz). The TLV320AIC3262 miniDSPs also enable advanced DSP sound enhancement

algorithms for an enhanced media experience on a portable audio device.

”

In my understanding, TLV320AIC3262 miniDSP supports AEC.

If TLV320AIC3120 mini DSP does not support AEC, it means that all Codec miniDSP are not equals?

Am I right?

The AIC3262 miniDSP is more powerful than the AIC3120 miniDSP.

We don't support AEC for any miniDSPs any longer.

Thanks for this Clarification

As no Codec supports AEC and I cannot change my SoC, I must introduce a DSP between the SOC and the CODEC to process the AEC.

Have you any recommendation for a low cost DSP to support AEC?
