Bluefish444 SDK
NVIDIA GPUDirect For Video
Bluefish444 and NVIDIA have long been a technology partners. NVIDIA GPUDirect developers can utilise Epoch Video I/O Cards and NVIDIA hardware together to deliver professional graphics over the highest quality SDI video.
NVIDIA GPUDirect for Video technology allows Bluefish444 hardware to communicate directly with NVIDIA GPUs. By taking advantage of this new API, the historical issues of introducing too much delay or latency are gone. With NVIDIA GPUDirect for Video, devices are fully synchronised, and the CPU doesn’t waste cycles copying data between device drivers. This flexible API gives full control to Bluefish444 hardware developers to stream video to and from the GPU at sub-frame transfer times.
Key Features
- Accelerated communication with video I/O devices
- Avoid unnecessary system memory copies and CPU overhead by copying data directly to/from pinned host memory
- Synchronised transfers between GPUs and Bluefish444 hardware
- Allow devices to work together without artificial wait-states to ensure completion
AMD DirectGMA For Video
Bluefish444 and AMD have long been technology partners. AMD DirectGMA developers can utilise Epoch Video I/O Cards and AMD hardware together to deliver professional graphics over the highest quality SDI video.
In today’s demanding media environment, creative professionals rely on powerful workstation solutions that offer outstanding graphics and computational performance to get high definition (HD) and ultra-high definition (UHD) video into the system for image processing on the GPU, and to play out the results as close to real-time as possible. Until recently, there was no method of transferring video directly between the GPU and Bluefish444 SDI I/O, and a two-step copy approach had to be applied instead, which created unwanted system latency. AMD via AMD FirePro professional graphics worked closely with Bluefish444 to develop DirectGMA, a technology that reduces latency in live/on-air broadcast graphics workflows and provides the necessary system bandwidth for demanding 4K and 5K digital cinema applications.
Key Features
- DirectGMA for Video support with an optimised pipeline for video devices such as Bluefish444 hardware.
- Makes a portion of the GPU memory accessible to Bluefish444 hardware.
- Allows Bluefish444 hardware on the bus to write directly into this area of GPU memory.
- Allows GPUs to write directly into the memory of Bluefish444 hardware on the bus.
- Use high-speed DMA transactions (peer-to-peer) to transfer data between the memories of the GPU and the Bluefish444 hardware.
