Description: The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of firmware [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA chip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.-The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented.

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。

Description: 由于微电子学和计算机科学的迅速发展，给EDA(电子设计自动化)行业带来了巨大的变化。特别是进入20世纪90年代后，电子系统已经从电路板级系统集成发展成为包括ASIC、FPGA/CPLD和嵌入系统的多种模式。可以说EDA产业已经成为电子信息类产品的支柱产业。EDA之所以能蓬勃发展的关键因素之一就是采用了硬件描述语言(HDL)描述电路系统。就FPGA和CPLD开发而言，比较流行的HDL主要有Verilog HDL、VHDL、ABEL-HDL和 AHDL 等，其中VHDL和Verilog HDL因适合标准化的发展方向而最终成为IEEE标准。-As the microelectronics and the rapid development of computer science, to the EDA (electronic design automation) industry, has brought great changes. Especially the beginning of the 20th century, 90 years, the electronic system has moved from the circuit board-level systems integration to develop into, including ASIC, FPGA/CPLD and embedded systems a variety of modes. Can be said that EDA industry, electronic information products has become a pillar industry. EDA has been able to flourish, one of the key factors is the use of a hardware description language (HDL) description of the electronic circuitry. On the FPGA and CPLD development, the more popular HDL mainly Verilog HDL, VHDL, ABEL-HDL, and AHDL etc., in which VHDL and Verilog HDL because of the direction for the development of standardization eventually become IEEE standard.
