Re-Customizing AXI Interconnects - 2022.2 English - UG1579

If you want the microblaze_1 instance of MicroBlaze to access the AXI block RAM Controller (axi_bram_ctrl_0), then the two interconnects instances must be reconfigured.

1. Double-click the AXI Interconnect (microblaze_1_axi_periph).

   The Re-customize IP dialog box opens.

2. From the drop-down menu, set the Number of Master Interfaces field to 2, as shown in the following figure.
   
   

   Similarly, re-customize the microblaze_axi_periph instance such that the Number of Slave Interfaces field is set to 2.

3. After that, you can connect the Master Interface M01_AXI of microblaze_1_axi_periph to the S01_AXI slave interface of microblaze_0_axi_periph.
4. Connect the clocks and resets accordingly as well, as shown in the following figure.
   
   

By doing this, you made the microblaze_1 access all the slaves accessible by microblaze_0. This is an optional decision.
