GPUDirect for Video technology helps IO board manufacturers write device drivers that efficiently transfer video frames in and out of NVIDIA GPU memory.

 

GPUs (Graphics Processing Units) are being used to accelerate complex and time consuming tasks in a range of applications from on-air graphics to real-time stereoscopic image reconstruction. Historically, however, getting data in and out of GPU memory from 3rd party hardware introduced unnecessary delay.

NVIDIA® GPUDirect for Video technology allows 3rd party hardware to efficiently communicate with NVIDIA GPUs and minimize historical latency issues. With NVIDIA GPUDirect for Video, IO devices are fully synchronized with the GPU and the CPU to minimize wasting cycles copying data between device drivers.

GPUDirect for Video technology is available to application developers through 3rd Party partner SDKs and gives developers full control to stream video in and out of the GPU at Sub-Frame transfer times in OpenGL, DirectX or CUDA on Windows or Linux.

Comparison of systems with and without GPUDirect for Video
 

Key Features

  • Avoid unnecessary system memory copies and CPU overhead by copying data through pinned host memory.
  • Synchronized transfers allow GPUs and video I/O devices to work together without artificial wait-states to ensure completion.
  • Reduce latency by transferring smaller chunks of the data, rather than waiting for the whole field or frame to be completed.
Operating System Windows 7, 8, 10, Server 2008R2, Server 2012, and Linux
Dependencies
