Qsys interconnect

I have a Nios II processor system with my own Qsys component which to monitor data memory access. The component has one slave (s1) (Nios data master is connected here) and one master (m1) (slave port...

Hi, You will need to know the base address from your Qsys system so that you can access them through NIOs II. Generally for accessing certain offset of a module, we will need to multiple the offset by 4 ie $base_addr + $offset * 4

    Hi

    Thank you for the response.

    Yeah, but I didn't mean that here.

    In my component, when I count, I am using conditions. At that point if I check the incoming address is within data memory address range, I could narrow down the extra counts. The address signal (avs_s1_address) coming from NiosII has only byte address. So if we can get base address signal also, we could figure out if any other address range is counted.

    Thanks
