avalon MM interface

Honored Contributor II

Hello All, 


I am trying to build a system using nios2, memory and a custom component with Avalon memory mapped interface. In the master side, it can be nios2 OR memory and the custom component is on the slave side. In the custom component, I have one slave port, it can be connected to more than one nios2 or memory. I hope arbitration between multiple masters & a single slave is automatically handled. But for my custom component functionalities, when signals come to slave port, I need to identify the master port (I mean where it is coming from). Can anyone help with this, please?
