摘　　要：为了研究基于PC的图形处理器(GPU)的通用计算技术,采用了基于纹理映射的经典GPU通用计算方法,进行了二维图像离散卷积和三维纹理映射体绘制的实验。实验证明了经典GPU通用计算技术在合适的算法设计基础上能够显著提升程序的运算速度,得出了基于CPU+GPU的异构计算模式可以成为高性能计算的一种选择的结论,展望了基于图形处理器的通用计算技术在未来的发展。In order to research the general purpose computing technology of GPU based on PC, the classic GPU general pur- pose computing method base on texture mapping technology was adopted, and the experiments of discrete convolution of 2D images and volume rendering based on 3D texture mapping were carried out. The experiment result indicates that, on the basis of a suitable algorithm design, the classic GPU general purpose computing technology can significantly enhance the program run- ning performance. In this article, it is concluded that the CPU＋GPU heterogeneous computing mode will become a choice for high- performance computation, and the further development of the general purpose computing technology based on GPU is prospected.
