Abstract
With the rapid development of the electronic technology, multimedia technology and network technology, video monitoring system is going to the embedded, digital direction. In this paper, a solution of embedded video monitoring system based on OMAP5912 is proposed. This solution makes full use of the advantages of dual-core of OMAP, which include ARM core and DSP core. Non-realtime task such as user interface and control unit is assigned to ARM, and realtime task such as video encoding is assigned to DSP. The capture and control task of the ARM side and the video encoding task of the DSP side are described in detail. The experiments demonstrate that the video encoding speed has been greatly improved by the proposed system comparing with the single ARM chip system. The frame rate of the monitoring system is increased in a large scale, and more suitable for the application in practice.
