摘要
通过Platform Builder定制支持Camera Interface模块P通道DMA的Windows CE 5.0系统。该系统适用于三星S3C2440平台,在S3C2440硬件平台上运行的Windows CE 5.0系统环境下,配置Camera Interface模块ITU-R BT656格式数据被剪裁和缩放并通过4个DMA通道实现实时视频数据的接收及"乒乓"数据缓存。并实现将数据缓冲区中图像数据在TFT-LCD上实时显示,最高分辨率可以达到640×480,实时显示速率达到22帧每秒。
Generate Windows CE 5.0 system which reserves DMA memory for CAMIF module through Platform Builder.The data which support ITU-R BT656 standard is Ping-Pong cached through four DMA channels after cut and preview scaled by CAMIF module on Samsung S3C2440 hardware platform and Windows CE 5.0 operating system.Real-time display the image data are cached by CAMIF DMA channel on TFT-LCD.The maximum resolution can achieve 640×480,the real-time display rate can achieve 22 frames per second.
