Description: 基于高速数字信号处理器(DSP) 和大规模现场可编程门阵列( FPGA) ,成功地研制了小型
化、低功耗的实时视频采集、处理和显示平台. 其中的DSP 负责图像处理,其外围的全部数字逻辑功能都集成在一片FPGA 内,包括高速视频流FIFO、同步时序产生与控制、接口逻辑转换和对视频编/ 解码器进行设置的I2 C 控制核等. 通过增大FIFO 位宽、提高传输带宽,降低了占用EMIF 总线的时间 利用数字延迟锁相环逻辑,提高了显示接口时序控制精度. 系统软件由驱动层、管理层和应用层组成,使得硬件管理与算法程序设计彼此分离,并能协同工作. 系统中的图像缓冲区采用了
三帧的配置方案,使得该平台最终具有对PAL/ N TSC 两种制式的全分辨率彩色复合视频信号进行实时采集、显示和处理的能力.-Based on high-speed digital signal processor (DSP) and large-scale field programmable gate array (FPGA), successfully developed a smaller, low-power real-time video capture, processing and display platform. One of the DSP is responsible for image processing, all its external digital logic functions are integrated in a FPGA, including high-speed video streaming FIFO, synchronous sequential generate and control, conversion and interface logic for video encoder/decoder to set up the control of nuclear and other I2 C. through increased FIFO bit width, increase the transmission bandwidth, reducing the time occupied by EMIF bus delay phase-locked loop using digital logic,

Description: 其实原理就是捕获屏幕画面然后再把图像传给客户机。原理很简单：
1、先利用hdc=GetWindowDC(NULL) 得到桌面的hdc
2、memhdc=CreateCompatibleDC(hdc) 根据桌面的hdc创建一个和屏幕相同的内存DC
3、StretchBlt(memhdc,0, 0, nWid,nHei, hdc, 0, 0,nWid,nHei, SRCCOPY) ，把屏幕的图像复制到内存DC这时你已经在内存中得到了屏幕的图像了。这是设备相关的DDB图像，如果希望转换成设备无关的DIB图像，只要在DDB图像前创建一个标准的BITMAP文件头就可以了（DDBtoDIB( bitmap, BI_RGB, pal )）。
4、得到图像数据（如果考虑速度的话可以把图像压缩）
5、数据传输（远程监控）
“在这里，我们先来看看截获当前桌面是如何实现的。关于远程捕获，只要在下面的基础上加上网络传输部分就OK了。下面介绍的是捕获桌面技术的基础，具体截屏代码如下：
-In principle is to capture screen picture then pictures to the client. Principle is very simple:
1, first using HDC detected by FCM (NULL) GetWindowDC = Get the desktop HDC detected by FCM
2, memhdc = CreateCompatibleDC (HDC detected by FCM), According to the desktop HDC detected by FCM create a same memory DC and screen
3 and StretchBlt (0, 0, memhdc, nWid, nHei, 0, 0, HDC detected by FCM, nWid, nHei SRCCOPY) , The screen, the image to the memory when you are already in memory DC got screen image. This is related to the equipment, if hope DDB image converted image of device-independent DIB in DDB images, before creating a BITMAP standard file header can (DDBtoDIB BITMAP, Pal, BI_RGB ().
4 and image data (if consider speed can put the image compression)
5 and data transmission (remote monitoring)
"Here, we ll look at how the desktop is intercepted. About remote capture, just below the basis and network transmission parts with respect to OK. Here is the foundation, the desktop
