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
