| Abstract: | 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. |
