LMS Block for Acitve Noise Cancellation

Hi,

I'm working on an active noise canecllation (ANC) System and I want to use a Sigma ADAU1442 Chip.

My first thought was to use the NLMS Filter Block. If i got it right, the algorithm looks like this:

For ANC it's desirable to use a FxLMS algorithm which is unfortunately not feasible with this block. Is it possible to add two pins like this?

Or create a smaller Block like this:

Thank you in advance.
