Development of the third-generation (3G) hand electronic products has great-ly broadened the application space of real-time graphics, while texture mapping is the most effective way to improve the sense of reality of graphics. Development of electronic technology has provided much more choice for the design of hardware acceleration chips. A texture mapping circuit was designed based on FPGA and using MIPmapping texture mapping algo-rithm. The circuit consisted of texture mapping address calculation, trilinear filtering and tex-ture memory. Comprehensive results showed its mapping speed can reach 41.145Mpixels/s and 329.16Mtexels/s for 24bits pixels.%随着第三代(3G)手持电子产品的发展，极大地拓宽了实时图形学的应用领域，而纹理映射是提高图形真实感最为有效的方法。电子技术的发展，为硬件加速芯片的设计提供了更多的选择。设计了基于FPGA的纹理映射电路，采用MIPmapping纹理映射算法，电路由纹理映射地址计算、三线性滤波和纹理存储器三部分组成。综合结果表明，对于24bits像素的绘制速度可达到41.145Mpixels/s和329.16Mtexels/s。
