摘要
在视频压缩编码算法的硬件实时实现中,针对专用芯片系统不够灵活、无法进行算法升级与更新等问题,利用双NiosⅡ处理器,主处理器完成管理功能和处理人机交互界面,协处理器做图像的编解码以及完成与计算机之间的数据传输,通过软硬件设计开发,实现实时图像采集系统。该方案算法易于升级,而且硬件系统也易于做相应的升级和更新,降低了系统成本。
In order to solve the problem that ASIC system is not flexible, and algorithm upgrades and updates can＇t be car- ried out, a real-time image acquisition system based on double Nios II processor was designed. The management functions and the man-machine interface were completed with the host processor, the image codec and the data transmission between computers were completed with the co-processor. The topology and hardware system are prone to upgrade and update, and the system cost is reduced greatly.
