摘 要 随着现今电子技术的快速发展，各式各样的电子数码产品层出不穷，人们生活的方方面面也离不开它们，与人们的生活息息相关。正是电子技术的不断进步与发展，驱使着数码相机以比较低廉的价格出现在市场上。现今，人们使用数码相机，一次拍摄下来往往就少不了上百张精美的图片，当图片存储在数码相机时，使用电脑来翻查所拍图片的操作比较繁琐，为了更便捷的观看到照片，电子相册就逐渐演变成电子数码相机的一种附属品，得到人们的热捧。与此同时，电子相册也能够大大节省传统打印照片的费用。 本课题是基于FPGA（Field Programmable Gate Array，现场可编程门阵列）技术设计的电子相册，选取Cyclone系列FPGA芯片EP1C3T144作为控制器，以SDRAM芯片K4S641632作为储存器，读取SD卡内部的图片数据，然后通过15针VGA接口送往LCD显示出图片，以实现简单的电子相册功能，让电子相册成为普通家庭摆设中的一道引人注目的风景线。 关键字 FPGA；电子相册；VGA；Cyclone Abstract With the rapid development of modern electronic technology, digital electronic products of all kinds has penetrated into every aspect of peoples life, and is closely related to peoples life.It is the continuous progress and development of electronic technology, driven by a digital camera with relatively low prices in the market.Nowadays, common family are in possession of a digital camera, and shooting down tend to store hundreds of beautiful pictures.Therefore,it is so more complicated when we use the computer to turn operation check the picture . In order to more convenient to watch the pictures, electronic photo album is a byproduct of people chasing hot digital camera.At the same time, the electronic photo album can also greatly reduce the cost of traditional print photos. This topic is based on FPGA (Programmable Gate Array Field, field programmable gate array) technology design of electronic albums, the system uses Cyclone series FPGA chip EP1C3T144C8 as the control processor, using SDRAM chip K4S641632 as the register, reading the internal image data of SD card , and then through the 15 pin VGA interface to the LCD display pictures, to achieve a simple electronic albums, can become a beautiful family scenery line.
