Echo Cancellation and SigmaStudio

Hi,

I would like to implement echo cancellation using the SigmaStudio platform and the EVAL-AD1940AZ dev board. In previous discussions dating back to 2011, it sounds like the only option is to start with an NLMS filter, and then build it yourself. I'm wondering if there has been any additional progress on providing support for echo cancellation, interm building blocks or sample code?

Thanks
