Bus throughput of i.MX8M Mini

[takayuki_ishii]

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?
