Free registration required

Executive Summary

The embedded motion detection system involves various aspects such as the selection of hardware platform and the embedded operating system. The development board with Samsung S3C2440 is selected as the hardware platform. Start-up codes, OS kernel and users' application programs are together stored in a NAND FLASH whose capacity is 64MB. Application programs run in 64MB SDRAM, which can also be used as the room of data and the stack. A CMOS camera capturing videos is connected to a USB interface in the board. After the captured video is processed by the detection module, they are transmitted to a local host through the Ethernet technology.
