| This paper presents an embedded system of face recognition from the actual requirements, which include framework, hardware (Circuit and driver) and software. The framework chapter analyzes the requirements of system and makes a choice about embedded processor (DSP). The hardware chapter introduces the external memory module and video I/O module, programs video-driver for the DM642 by using CSL, discuss the applications of interrupt and direct memory access (DMA). The software chapter introduces the principle of face recognition algorithm, and discusses the problems of algorithm optimization and software porting. |
