基于NIOS技术的流水灯LED显示系统的设计.pdf

吾日三省乎吾身。为人谋而不忠乎？与朋友交而不信乎？传不习乎？——《论语》 基于 NIOS技术的流水灯LED显示系统的设计 ： 内容提要 随着电子技术的不断发展，电子产品向体积越来越小、设计时间越 来越短、集成度越来越精密、产品周期越来越短、成本越来越低、功能越来越强 大等方向发展。使用 NIOSⅡ处理器的用户可以根据他们的需要调嵌入式系统的 特性、性能以及成本，快速使得产品推向市场，扩展产品的生命周期，并且避免 处理器的更新换代。 本论文结合EDA技术、C语言、NIOSⅡ技术、计算机技术等多种技术实现基 于NiosⅡ的系统设计。并用LED流水灯显示来检验我设计的NIOSⅡ技术的系统 功能。同时也为其他相关项目的设计提供了参考。 关键词：EDA技术 SOPC技术 NIOSⅡ处理器 嵌入式技术 LED显示 NIOS Ⅱ technology-based systems design and implementation of - LED light water show Abstract：With the continuo us development of electronic technolo gy, electronic products to the size is getting smaller and smaller, shorter and shorter design time, more and more sophisticated integration, product life cycle is becoming shorter and shorter, more and more low-cost, more and more powerful features, such as Direction. The use of NIOS Ⅱ processor users based on their need to transfer the characteristics of embedded systems, performance and cost of making products to market quickly, expand the products life cycle and to avoid the replacement of the processor. This thesis EDA combination of technology, C language, NIOSⅡ technology, computer technology and other technology-based Nios Ⅱ system design. And the LED light water show designed to test my NIOS Ⅱ technology system.
