Hello community,
Our customer hope to know a bus throughput of i.MX8M Mini.
So please suggest following bus width and clock frequency of each bus master peripheral.
1. CPU - AXI switch fabric
2. DDR - AXI switch fablic
3. PCIe - AXI switch fablic
I can found only 2.DDR - AXI.
In reference manual 9.1.1.1 DRAM Interface,
• 750MHz 128-bit AXI bus
But other 1 and 3 connection of master device can not found.
Do you mind explaining this in more detail?
Best regards,
Ishii.

Hi Ishii
>But other 1 and 3 connection of master device can not found.
it is the same as described in "9.1.1.1 DRAM Interface", since for interconnections
main NoC is used as central inter-connect fabric, which runs at 750MHz.
>Do you mind explaining this in more detail?

Can I get a AXI bus width?
Is it need to ask local FAE?
