2009-05-07 23:44:50     I2S vs AC'97 on Blackfin

Hi,

 

I would like to get an opinion on the CPU load for Blackfin comparing I2S codec and AC'97 codec  while when running a same application on the BF537.

 

(i dont know if this is the right question even, and if the cpu load is same...)

 

I currently have an AD73322 codec on my board, and am considering redesiging it with AD1981BL.

 

Thanks,

AC'97 will be much higher load.

I used AD1981BL. It's perfect.

 

But AC97 Code's SNR is about < 100dB, If you  get high quality(SNR > 100dB) you must using I2S codec.

 

Good luck!
