Design and development of video display system based on CUDA technology

CUDA(compute unified device architecture)launched by NVIDIA is a development platform based on the GPU for general-purpose computation and suitable for large-scale parallel data computation. The parallel processing compression algorithm is implemented by CUDA under the stream processor architecture of GPU. The optimization of reading and writing memory was carried out according to the features of the stream processor architecture. The software mosaic system with multi-screen fusion display in the computer's desktop environment was achieved with CUDA technology. A software-system based on the CUDA technology is introduced. This system is more powerful than any previous video fusion systems,and cheaper than the hardware-assisted fusion system such as VGA. The experiment shows that the CUDA technology has the advantages of parallel processing to make this system has fast real-time image processing and interactivity. It will be widely used in business filed.
