Software ISP i.MX.6 bayer -> YUV

Hello,

I am looking for a software ISP solution to convert bayer camera sensor format to YVU on i.MX.6Q.

I've read through other discussions about the fact that IPU doesn't support convert bayer to YUV on-the-fly.

I've came across a application note from the soon to be released i.MX.8 platform, which talked about a software ISP implementation which uses OpenCL. https://www.nxp.com/docs/en/application-note/AN12060.pdf 

Since it's OpenCL, I would expect it will work on i.MX.6Q(i.MX.6 does support OpenCL 1.1EP) as well. 

Would be much appreciate if you guys can provide source code of that application note? 

Regards,

Youxin

Hi,

You can check this GStreamer-based bayer interpolation plugin for i.MX6. It uses the GPU for acceleration.

Hi Youxin,

Document have information about Opencl and OpenVX, that is supported by i.MX8.

There is no i.MX8 for graphics yet, however you can download the GPU utilities for MX6Q: 

IMX6_L4.1.15_2.0.0_GPU_TOOL

Hi

Thanks for your reply. However, I don't think that answered my question. 

What I'd like to have is the source code of the opencl backed project described in that application code. I understand that is tested only on i.MX8 platform. I'd like to test it on i.MX6 as there is a good chance that it may work on i.MX6 GPU as well.

Thanks,

Youxin

Hi,

you probably found it by now, but for future reference: gtec-demo-framework/DemoApps/OpenCL/SoftISP at master · NXPmicro/gtec-demo-framework · GitHub
