摘要
为了在DSP平台上实现实时大图像旋转,结合TMS320DM642的性能结构特点,针对旋转算法中严重影响DSPCPU效率发挥的大量非连续图像像素地址访问的问题,提出了基于视口图像块覆盖的DSP图像旋转算法数据调度策略,对算法的结构流程进行了优化调整。
In order to realize real-time rotation for big image on DSP, combining with the configuration characteristics of TMS320DM642 and aiming at the non-sequential pixel address accessing problem which affects the efficiency of CPU badly, this paper presents a data attempter tactic of image rotation algorithm based on the overlay of view port image block which can optimize the algorithm structure flow.
