I'm working on implementing an active noise control algorithm. I am currently working on an ADSP-221489 EZKIT LITE, because we had one lying around. I am quite new to these things, but I am beginning to suspect that this board and the AD1939 codec on it are not quite suited to my application. I got the algorithm to work, but I feel the system is not working as well as it could be, mainly due to latency issues. I am wondering which hardware would be better for me. I hope you can help. Below I have listed some information about my application:
- Active noise control system with adaptive controller and adaptive plant model.
- Preferred sample frequency: 8 kHz.
- 2 ADCs/input ports.
- 2 DACs/output ports.
- Low latency (currently multiple ms's)
If you need more specific details to answer my question, please let me know.
I have experienced the issues caused by using a slow sample rate. I agree running at a higher sample frequency is better, however I am slightly limited by the necessary filter lengths.
Anyway, I have looked at the documentation of the evaluation boards and especially for the 21489 EZLITE board I am having trouble finding evidence of a header that would allow me to connect it to the 1772.
