How to implement a NxM Mixer with no. of inputs & outputs more than 16 in 21489

Dear Team,

I would like to know how to implement a NxM Mixer where NxM is 32x32 because what I found in teh TreeToolBox , the NxM Mixer can grow up to 16 Inputs and 16 Outputs only. So my questions are :

1. I am not very sure whether it is still possible to implement bigger size Mixer in 21489 EVB . The following are the version we use now :

Sigma Studio Ver 3.14 Build 2 Rev 1690

Sigma Studio For SHARC Rel 2.2.0

HW - ADSP 21489 EVB

2. As I heard there is a module called Audio Signal Router which is suggested to be used to replace NxM Mixer module , but I cannot find it in SigmaStudio ToolBox . Do you have any idea about it ?

Thanks

Regards,
