By adding usb pc camera to PXA255 development board, car black box is implemented in this paper. The proposed car black boxrouter is developed based on the Xscale PXA255 processor, and the embedded Linux is adopted as an operating system. The program which stores and display the image before and after accident, is redesigned from mvc-0.8.9

When produce traffic accident in blind area of camera in occasion of black box system that is used commonly present, degradation of system can not but be unavoidable. System of this study helps as can analyze occurrence cause of traffic accident exactly by offering filming and stores image of accident all directions of vehicles giving intelligence on camera module. Also, can take witness' role, and prevent insurance fraud.
Ad-hoc 방식의 PCMCIA 인터페이스에 의한 저가형 Wireless Network 구현에 관한 연구

By removing PCMCIA dedicate controller chip from Ann processor based embedded linux system, a cost effective embedded system is implemented in this paper. we propose PCMCIA interface architecture by using Ad hoc methods for wireless network. The proposed system is developed based on S3C2410A processor and it is interfaced with PCMCIA socket by using combinational digital logic circuits. It shows that Ad hoc interface provide almost same performance compare with dedicate controller. The result indicates that proposed method simplifies the system without the loss of the performance.
