Abstract: Digital video monitoring system is widely applied due to its intuition,convenience and colorful information.The author uses DSP+ARM binuclear structure,TMS320DM642 in image acquisition and processing,and AT91RM9200 in real-time control.The video image of a certain area is acquired by DSP through CCD camera,and video decoding is finished by relevant chip.The processed digital video signals are processed by DSP through video montion detection algorithm.If there is abnormal condition,DSP will transmit interruption signal to ARM,which performs real-time control over DSP image acquisition and helps to show the image processing results.ARM can trigger external controller and then can achieve external control.Experiments show that this system is stable,reliable,and feasible.

Key words: DSP+ARM, inserting system, binuclear structure
