摘要
利用FPGA控制视频解码芯片ADV7183A,从而输出8 bit的YCrCb型4∶2∶2的视频数据,再将其进行隔点采样,得到320×256的灰度图像数据,并传输给DSP,由DSP显示的采样数据达到设计要求,为后来的滤波处理提供良好的数字视频数据。
FPGA is used to control ADV7183A so that ADV7183A can output the 8 bit 4∶2∶2 YCrCb video data.Then the data is sampled at every other point to produce the grayscale image data of 320×256.Finally,the data is transmitted to DSP.The sampled data displayed by DSP meets the demand of design and serves as good digital video data for later filtering.
