Processor for USB DAC

[ATAineri]

I am an student of BMSTU. Now I'm developing DAC for my graduate and now have a challenge of chosing processor. There is no documentation or datasheet for imx7ULP. I need in information about its power consuption in normal and low power modes. Is it has more power consuption than imx6UltraLite? And one more question about this two ones. Are thay have mechanism for regulate its clock frequency and power consuption besides low power mode?

What is the best NXP processor for android DIY audio player?)

Hello,

  The i.MX7ULP is not launched yet. Only preliminary information is available now on the following Web:

i.MX 7ULP Applications Processor | Single Arm® Cortex®-A7 + Cortex-M4 with ultra low power |NXP 

  According to preliminary measurements on early silicon, power consumption of i.MX 7ULP is lower, than for i.MX 6UL.  

     Linux CPUFREQ feature also applied to i.MX 7ULP.

  As for the audio player - basically NXP i.MX series is intended for multimedia applications.

Regards,

Yuri.
