NVIDIA Performance Primitives

The NVIDIA Performance Primitives library (NPP) is a collection of GPU-accelerated image, video, and signal processing functions that deliver 5x to 10x faster performance than comparable CPU-only implementations. Using NPP, developers can take advantage of over 1900 image processing and  approx 600 signal processing primitives to achieve significant improvements in application performance in a matter of hours.

Whether you are simply replacing CPU primitives with GPU-accelerated versions or integrating NPP primitives with your existing GPU-accelerated pipeline, NPP delivers high performance while reducing your development time.

Examples
