TX1 camera data to GPU memory directly

Is TX1 supports the direct data transfer of data from a camera module to the GPU memory directly without using the CPU memory path?

Is there a similar technology in TX1 board like ‘NVIDIA GPUDirect’ which is using dma for transferring frame data from camera(VI)/ISP to the Maxwell GPU to process the frames using CUDA ?

Hi Sijo,

GPUdirect is not supported in Jetson TX1, and the existing Tegra shared-memory architecture might be sufficient.

Would you please describe your use case clearly? Then we can provide the suggestion accordingly.

Thanks

Thanks kayccc,

Can you please explain about ‘Tegra shared-memory architecture’

I want to get the frame data from camera(s) connected in MIPI interface directly to GPU. As per spec, 6 cameras can be connected to the Jetson TX1 MIPI interface, whether the frames obtaining from the camera(s) is directly available in GPU for the processing in CUDA.

Thanks

Hi Sijo,

Please refer to the post in below topic:
