摄像头的工作原理大致为：景物通过镜头(LENS)生成的光学图像投射到图像传感器面上，然后转为电信号，经过A/D(模数转换)转换后变为数字图像信号，再送到数字信号处理芯片(DSP)中加工处理，再通过USB接口传输到电脑中处理，通过显示器就可以看到图像了(The working principle of the camera is roughly: the scenery through the lens (LENS) optical image onto the image sensor surf

用于ti c55x dsp的静止图像jpeg算法中的正向余弦变幻的实现,(Used in the static image jpeg algorithm of the ti c55x DSP is the realization of the cosine fluctuates,)

dsp来完成图像压缩,有利于满足实时要求,不错的(DSP to do image compression, which is beneficial to satisfy the real-time requirement, good)

基于BIOS/DSP的嵌入框架，将MT9M001的CMOS图像传感器连接至DM642的一个VP口上，并实现RAW数据流采集，使用SAA7105H视频编码器编码成ITU-BT656格式的视频流，实现AV和VGA实时显示(The embedded framework based on BIOS/DSP and CMOS image sensor MT9M001 is connected to a DM642 port VP, and implement the RAW data stream cap
