基于FPGA的3D光立方设计

摘要

A 3D light cube system based on FPGA controller core is presented. According to the dynamic patternrndisplay in the 3D LED matrix function, the internal algorithm has been properly designed with the application ofrndual Nios II soft cores. The system completes high-speed graphics processing and extends peripheral interface suchrnas touch screen,the PS/2 keyboard, audio players and so on. The platform provides good visual and entertainmentrnexperience combined with application development such as 3D Snake,3D text display and so on.%设计开发一种采用FPGA作为控制核心的3D光立方显示器方案.根据针对3维LED点阵进行动态图案显示的功能需求,对FPGA内部算法进行合理划分及处理,利用双NiosⅡ软核完成了高速图形处理及触摸屏、PS/2键盘、音频播放等大量外设接口,实现了一个完整的综合信息平台.结合3D贪吃蛇游戏、3D文字和图像动态显示等一些应用开发,本光立方显示平台提供了良好的用户视觉与娱乐体验.
