SOPC realization of image acquisition and real-time network monitoring system

According to the monitoring system widely adopted now which has much weakness, such as transmission distance limited, low speed of acquisition and processing, and poor stability, this paper puts forward a design scheme about image acquisition and real-time network monitoring system. First of all, the system integrates the image acquisition, storage, compression and transmission and other hardware circuits into a piece of FPGA chip by SOPC technology. Second, embedded operating system MicroC/OS-II is as software platform of the system, then the sysytem adopts the standard socket interface, and through LWIP protocol stack transports image data. Characters of this system is: first, optimizing the 2D-DCT transform, and realizing it by C language based on Nios II processor in the uC/OS-II, not only compression image but also improveing the image compression rate. second, transmission image data by ethernet, so it conveniently realizes the remote communication.
