multirate process adau1451

hello everyone

can someone explain how to use the new multirate feature in SigmaStudio 3.12  and adau1451, upsampling is possible?

My project is running at fs48k, i need some process at 192kz , for example pass through FIR filter at 192

My next hardware stage run at fs192, but this stage is full and i need more process capability.

thanks

Nico
