[FAQ] TLV320AIC CODECS and ADCs: How do I develop code for the miniDSPs inside the TLV320AIC CODECs and ADCs?

To start miniDSP code development, you need to:

1. Obtain an EVM:

TLV320ADC3101EVM-K
TLV320AIC3111EVM-K
TLV320AIC3120EVM-U
TLV320AIC3253EVM-K
TLV320AIC3254EVM-K
TLV320AIC3254EVM-U
TLV320AIC3256EVM-U
TLV320AIC3262EVM-U
TLV320AIC3263EVM-U
TLV320AIC3268EVM-U
TLV320AIC36EVM-K
PCM3070RHBEVM-K

2. Obtain access to the PurePath Studio software: http://www.ti.com/tool/aicpurepath_studio. This will also provide access to documentation.

3. (Optional) Obtain the EVM Control Software (found on each link above) to easily configure the device registers.

4. Run PurePath Studio and enjoy!

These devices can be configured extensively to allow the lowest power consumption. One of this methods is to adjust the number of cycles per frame of the DSPs. However this has restrictions that need to be taken into account as explained here:  https://e2e.ti.com/support/audio/f/6/p/773090/2859067?tisearch=e2e-sitesearch&keymatch=%20user:35731#2859067

Coefficients can be changed on the fly with an MCU thanks to the Adaptive Mode of these parts. More information can be found in this app note and in this FAQ:  https://e2e.ti.com/support/audio/f/6/p/773127/2859157#2859157

Hope this helps!
