为了使学校学生在实践中学习应用指纹采集实验技术,并将指纹采集到计算机上进行显示。文章给出了基于TI公司的16位定点DSP芯片TMS320VC5416的实验系统设计方案。详细介绍了系统的组成和各个模块的硬件及接口设计方法,并在此基础上对指纹采集实验内容进行了说明。结果证明:该实验系统是进行学习和开发的实用工具。
In order to enable school students to learn in practice the application of fingerprinting experimental techniques, and fingerprinting to the computer for display. The article gives the experimental system design based on TMS320VC5416 16-bit fixed-point DSP chip TI company. The composition of the system and the hardware and interface design methods of each module are introduced in detail. On the basis of this, the experimental contents of fingerprint acquisition are described. The results show that the experimental system is a practical tool for learning and development.
