摘　　要：近年来,图形处理器(GPU)的发展日益成熟,应用范围不在局限于计算机图形学本身,已逐步扩展到通用数值计算领域。本文介绍了最新GPU用于通用计算的原理和方法,并在图像处理和科学计算方面对GPU和CPU算法进行了计算速度的对比研究,实验结果表明GPU在通用计算领域相对于CPU具有明显优势。Recently, the development of Graphics Processing Unit （GPU） has become more and more sophisticated. The scope of application of GPU has been expanded to general purpose computations, except from those applications in graphics itself. In this paper, a detail introduction is given to the principles and methods of general purpose computation by GPU, and a comparative study of the calculation speed of GPU and CPU algorithm in image processing and scientific computing is made, and the experimental results show that GPU has an obvious advantage in general purpose computing compared with CPU.
