摘　　要： 嵌入式指纹识别是目前指纹脱机系统的研究应用热点,其核心是DSP系统.本文就此采用TI的高速DSP芯片TMS320VC5410集成开发环境(IDE)CCS 2.2对其实现进行了研究,并用极值滤波、平滑滤波、拉普拉氏锐化、二值化对指纹图像进行预处理.系统EVM测试得出,预处理的时间为0.18～0.3s,需要DSP CPU资源为约30000MIPS,达到了DSP实现指纹识别实时性能要求. The embedded fingerprint identification system is the focal point at the moment. Its core problem is the DSP system. This paper uses the TI TMS320VC5410 as the core chip to develop the program of fingerprint recognition. In this paper, the algorithm of fingerprint recognition uses the IDE that is code composer studio2.2 （CCS2.2）. After the previously processing which includes extreme filter, smoothing, Laplacian sharpening and binalization, a good experiment results is got. The system is measured to take 0.18-0.3s for fingerprint pretreatment and needs approximately DSP CPU 30000MIPS. Thereal time recognition of fingerprint by DSP is realized.
