Abstract—Constructing a intelligence surveillance system using embedded video server requires a sophisticated hardware/software framework for this system, and it should consider the performance, cost and energy/power consumption constrains. This paper discusses the design and implementation of an intelligence surveillance system which uses embedded multimedia server as core computing platform. We have carefully designed the embedded server based on MPSoC platform for the surveillance system whose key functionalities include heterogeneous multiprocessors environment set up, key algorithm porting and development framework design. The heterogeneous multiprocessors environment setup provides memory/communication management among multiprocessors to enhance the programmability of platform. Using realize/optimize the video encoding algorithm and porting to the TMS320DM6446 chip to guarantee the availability of media streaming system based on network. The hardware/software development framework provides an adequate mechanism which models signal processing in video surveillance system as process network and provides integrated homogeneous abstract programming environment. The proposed system has been implemented on an MPSoC platform and it is fully operational. The design principles of the whole system are validated with real experiments, and the performance characteristics are analyzed.
