摘要
在现有指纹识别算法的基础上,根据嵌入式的特点,通过软件算法的加速以及系统硬件的配置优化来实现板级的指纹识别系统。通过交叉编译器把二进制代码转化为适合于power-pc405 core类型的数据,采用SDK工具Xilinx XUP Virtex-Ⅱ Pro Development System开发板协同仿真。在软件算法加速优化的基础上速度得到了很大的提高。
On the base of fingerprint arithmetic,according to the characteristic of embed the system of fingerprint distinguish is implemented.Binary code is converted by cross-compiler to the kind of data fitful for powerpc405 core.Using the tool of SDK——Xilinx XUP Virtec-Ⅱ Pro Development System development board does HW/SW co simulation.The speedup of software arithmetic and the configuration of hardware improve the performance of fingerprint distinguish.
