I try to program SRC on ADSP21469 similar to the EE-268 example1(Programming Asynchronous Sample Rate Converters on ADSP-21364).
The signal just like:----->SPORT0------>SRC0(48KHz to 96KHZ)----->SPORT1.And I take I2S module.
(1) 48KHZ --->48KHZ
from the pictures, that when 48KHZ---->48KHZ ,it has noise. But 48KHZ---->96KHZ,it get a wrong answer.
I have no idea about this. What is wrong with it?
I hope someone can give me some advise. Thank you very much!
