Description: 在ASIC设计中常常会用到双向IO口来节省系统的硬件资源。但很少有书籍对INOUT口的程序设计和仿真进行介绍，同时，一些书籍介绍的方法在实际中无法使用，本文通过一个图象传感器的事例来详细说明INOUT口的设计方法，并提出一些与实际情况相符的仿真方法-In ASIC design often used in bi-directional IO port to save the system s hardware resources. However, very few books on INOUT mouth design and simulation procedure is introduced, at the same time, a number of books to introduce the method in practice can not be used, the paper through an example of image sensor to a detailed description of the design method INOUT mouth and put forward some actual position in the simulation method Platform: |

Description: 本项目名称是：基于FPGA的指纹识别模块设计。
主要内容为：本模块采用xilinx公司的Spartan 3E系列XC3S500E
型FPGA作为核心控制芯片，通过富士通公司的MFS300滑动式电容指纹传感器对指纹图象进行提取，然后对提取的指纹图像进行灰度滤波、图像增强、二值化、二值去噪、细化等预处理，得到清晰的指纹图象，再从清晰的指纹图象中提取指纹特征点，存入外部FLASH作为建档模板。指纹比对时，采用同样的方法获得清晰的指纹图像，建立比对模板，然后将比对模板与建档模板利用点模式匹配算法进行比对，得出比对结果。该模块利用嵌入式软核实现系统的管理，利用硬件实现指纹识别，保证了系统功能的完整性与识别的正确性。该识别模块可用于门禁、考勤、安检、保险箱柜等很多方面，也可和计算机等设备联机使用，满足各个方面的不同需求，因此它的设计具有很广泛的应用前景和市场价值。
-The project name is: FPGA-based fingerprint identification module design.
The main contents are: the use of this module xilinx s Spartan 3E Series XC3S500E
FPGA-based control chip as the core, through the MFS300 Fujitsu fingerprint slide sensor capacitance extraction of the fingerprint image, and then extracted gray-scale fingerprint image filtering, image enhancement, binarization, denoising Second, refinement, etc. pre-treatment have been given clear fingerprint image, and then a clear fingerprint image from the extracted fingerprint feature points, into the external FLASH file as a template. Fingerprint matching using the same method to obtain a clear image of the fingerprint to establish than the template, and then will be the template file templates and the use of point pattern matching algorithm than the right, than the results obtained. The module is the realization of the use of soft-core embedded system management, the use of fingerprint recognition hardware implementation Platform: |
