MIMX8MQ6CVAHZAB || Use Case support

JyotiVaishnav — Mon, 18 Sep 2023 07:15:40 GMT

Hello NXP team,

We are using a part MIMX8MQ6CVAHZAB in our design.

We have a use case of 4 Camera Decode (1080p30) + Compute (Offloaded to AI Accelerator) + CPU Post processing (overlay / bounding box) + Composite view to the display.

Along with the above use case if the encoding is also required, do you have any recommendations of an SoC in the iMX8 Family?

Hello NXP Team,

Can you please update on use case support.

So, what is the requirement of the encoding?

I think i.MX8QM could meet your requirements.

Hello @jimmychan

Thanks!

i.MX8QM - It is an high rated processor.

i.MX 8M Quad or i.MX 8M Plus Quad out of this two processor any one can meet our requirements?

i.MX8MP is better. It has NPU for machine learning task. 2 x MIPI-CSI could connect two cameras. Other cameras could connect via Network (IP cameras to GB Ethernet on 8MP) and USB could connect one.

Hello @jimmychan

We want to know one more thing, According to our use case which is the best suitable processor for our design.

out of below two process which is the best suitable for our design.

MIMX8ML8CVNKZAB

MIMX8ML6CVNKZAB

Your feedback is important for us.

It depends which OS will you using. There are Android and Linux BSP. And what kind of application will you run on your system to capture and compute the data. So it is better to buy the i.MX8MP EVK to develop and run your applications on it. It would more accurate to check how many memory and EMMC spaces will need for your use cases.

This table is in the datasheet. Do you need the NPU? if need, then select the part number that include the NPU.
