Hello,

Are CUDA, Nvdec, and Nvjpg hardware decoders related?

Thank you.

Hi,
These are independent hardware blocks. Are not related. For hardware architecture, please check

Hello,

I know the hardware decoder uses hardware acceleration

Doesn’t the hardware decoder use cuda internally?

cuda can only be used when coded using cuda syntax, right?

Thank you.

This is a tegra x1 processor block diagram. Can I check cuda here?

Thank you.

Hi,
NVDEC is independent hardware decoder and do not use GPU. CUDA is the interface of using GPU engine. A compiled/run CUDA application is executed on Maxwell GPU.
