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!
