Abstract

Based on chip of TMS320DM6446 and Embedded Linux system, an embedded device was designed to establish software and hardware platforms of multimodal visual biometric features capture interface. The research is concerned about hardware circuit design and software drivers design of OV9620 and standard compound video. Eventually, experiment proved validity of the implemented device.
