Ask TDA4VM VPAC question

Hello，

When I check TDA4VM document that,there has two pictures:

I want ask how many VPAC on TDA4VM in total? and one CSIRX instance mapping one VPAC?

TDA4VM has two CSIRX,is there two VPAC node?and how to understand the multi camera case VISSX4?one VPAC has max 4 VISS?

If it is one CSIRX instance mapping one VPAC, could it support two CSIRX image data input into one VPAC node to process?if support any demo or code can be share to me?

thanks
