NVIDIA is pleased to announce the release of version 1.0 of the NVIDIA Performance Primitives (NPP) library.Performance primitives are foundational building blocks for performing GPU accelerated processing. The initial set of functionality in the library focuses on functions for imaging and video processing and is widely applicable for developers in these areas. The NPP library is written to maximize flexibility, while maintaining high performance.NPP can be easily integrated into existing applications and allows developers to take advantage of GPU acceleration without having to write code for the GPU.The functions contained in this version span fundamental operations such as add, multiply and divide to advanced operations such as perspective warps, discrete cosine transformation, histogram and Canny filtering.The library currently supports Linux 32/64, Windows 32/64 and Mac OS and is available at www.nvidia.com/npp.Please note that the Linux version of this release has been tested on only CentOS 4.7 but is expected to run on other distros as well.
