Use Neon to implement memcpy to copy image frames

Hi , vendor:

Our platform is Jetson AGX.

In user space , we use ring buffer mechanism in V4L2 to get captured frames and copy the frames to user space application software block.

We want to improve the performance of memcpy , we know AGX is with ARMv8 and ARMv8 is with Neon.

So , if we want to implement our own memcpy based on Neon , what should we do?? Is there any sample code??

Thanks for suggestion

I would suggest avoid memory copy for hurting the performance would be the good way.
