dpuczdx8g v4.1 compatibility consultation about vitis-ai HOT 7 CLOSED

@Yuxin-Yu we have done limited testing, but yes, we can confirm that the DPUCZ IP can be implemented on a Zynq-7000 device with a minor patch to the Vitis AI Library.
vitis-ai-library.zip

Thank you @quentonh . In addition, in order to make dpuczdx8g v4.1 compatible with zynq 7000, I have changed some related parameters, as shown in the red circles in the following two figures. Is that right?

from vitis-ai.

Also, it should be noted that I am using Vitis AI 3.0 version. Are the patch files used the same? @quentonh

from vitis-ai.

@Yuxin-Yu we have not internally verified the patches against Vitis AI 3.0, but the modifications to the Vitis AI Library will be very similar if not identical. The required changes result from differences in the NEON instruction set between the Cortex A53 (ZU+) and Cortex A9 (Zynq-7000). You should do compare between the modified source files in the two releases (3.5 and 3.0) to ensure that the changes apply.

With regard to integration into a hardware platform, I can send you an example. Please drop me an email to quentonh at amd.com.

Hi @quentonh .I don't know how to send email at amd.com.If possible, you can send the example to my email : [email protected] .Thank you.

Hello @quentonh , I successfully ran the resnet50 inference process using zynq7000, but the inference result is incorrect, as shown below:

root@debian:~/Vitis-AI/src/vai_runtime/vart_debug/softmax-runner-cpu/test/resnet_v1_50_softmax_cpu# ./run.sh ~/app/img/bellpeppe-994958.JPEG

score[488]  =  0.0247368    text: chain,
score[679]  =  0.0150036    text: necklace,

What could be the reason and how should I debug it?

Problem solved, it's because my xmodel file was used incorrectly
