摘　　要：在FPGA平台上,设计了包括坐标旋转引擎和双线性插值器的数字图像旋转系统。阐述了基于CORDIC算法坐标旋转引擎的设计原理,并采用高速的流水线架构实现上述电路。综合后的仿真结果表明,旋转后的图像色彩丰富,细节部分清晰,可望达到100帧/s的速度,满足高分辨率实时应用场合的要求。An FPGA implementation of image rotation is designed. The design includes a coordinate rotation engine and a bilinear interpolator. The coordinate rotation engine, which implemented in pipeline way to achieve high throughput requirement,is based on CORDIC algorithm. The simulation result indicates that, the rotated image has high definition.The frame rate which can reach 100fps/s, to satify the real-time and high resolution constraints.
