Inter processor communication (Between iMX8MQ and i.MX8MQ) design

Hi NXP Team,

We are planning to establish an inter-process communication between two i.MXMQ series processors.

  • Approach-1:
    • The first approach is to establish connectivity via MAC(RGMII) interface. 
  • Approach-2:

Queries:

  1. In the i.MX6Q references the results mentioned below. Will we get similar results in i.MX8Q? pastedImage_4.png
  2. What throughput we can expect in approach 1? (Using RGMII connections?)
  3. Which design is better for inter-process communication between two processors(The communication would be of non-video data)? 

Regards.

Hi Harshit

1. yes

2. i.MX8MQ has not rgmii issues/errata, so rgmii performance can be obtained

3. seems for short distance pcie is better (less wires), for longer distances probably

rgmii better as it imposes less requirements on board/cable/connectors quality

to avoid signal loss.

Best regards
igor
