Software development is oriented to use Qt library from Nokia’s Qt Development Frameworks and C++ for Microsoft Windows platform. The project decisions of realization data acquisition and processing algorithms are presented both for the traditional uniprocessor systems and the facilities of CUDA library (NVIDIA) extended due to bringing in for graphic processors. ȼɜɟɞɟɧɢɟ * ! , " $+9 %&' , , Qt- !
