【摘要】 数字家庭系统是集计算机、通信、消费技术于一体的3C(Computer, Communication和Consumer)系统,它实现了家庭中各种可能的设备之间的信息交换和远程监控。对数字家庭系统平台的研究的突破,将有可能在以后的竞争中占据制高点,取得良好的经济和社会效益。经过一年的研究工作,基本上实现了基于Blackfin DSP的嵌入式数字家庭系统平台。Blackfin处理器是新一代嵌入式处理器,是美国模拟器件公司(ADI)与Intel联合开发的首款第四代DSP产品,采用全新的微信号结构(MSA)架构。Blackfin处理器及其延伸产品适合在功耗、性能、成本和运算能力等综合要求比较高的音频、视频和通信领域的应用。本论文的研究内容是利用Blackfin系列DSP处理器的高性能、低功耗、支持动态电源管理等特点以及嵌入式Linux开放源代码、系统内核小、内核网络结构完整等突出特点,建立一个高速的基于Blackfin的嵌入式数字家庭系统平台。首先简单介绍了数字家庭概况以及课题研究的意义;其次从硬件平台和系统软件两个方面阐述了数字家庭的系统平台基础;接着描述了基于Blackfin的嵌入式数字家庭系统的硬件总体设计和子模块设计;然后重点论述了uClinux操作系统在数字家庭平台上的移植与实现;最后详细介绍了嵌入式图形用户界面GUI——Microwindows的移植和实现。更多还原

【Abstract】 Digital home system is called 3C (Computer, Communication and Consumer) system, which include computer, communication and consumer technology. It connects all kinds of possible equipments to realize information switching and remote survey and control. If we take the research of digital home system platform as a breakthrough, it is possibly that we can win a great advantage over other opponents in the future competition and gain great social and economic benefit. For this purpose, our paper design and implement the embedded digital home system based Blackfin DSP.The Blackfin processor is the new generation Embedded processor, which is developed by the American Analog Device limited company (ADI) with Intel, the first section fourth generation of DSP product, using the brand-new Micro-signal structure (MSA) construction. The Blackfin processor and its extends the product are suit to the application which require lower power dissipation, the high performance, the low cost, and the high operation ability and application of quite high audio frequency, video frequency and communication system.The paper’s research content is uses series DSP of Blackfin’s characteristic such as high performance, low power dissipation, support dynamic power source management and the embedded Linux’s characteristic such as the open source code, the little system kernel, the entire network structure in the kernel code, establishes a high speed embedded digital home system platform based on Blackfin. The paper introduces the conception of digital home and its development and significance at first. Then it explains the foundation of digital home system platform based on hardware platform and system operation system. Following it talks about the frame hardware system design and the daughter module board of the embedded digital home system platform based on Blackfin. After that, it mainly explains the uClinux kernel’s transplantation and realization on the digital home system platform. At last it introduces the embedded GUI—microwindow’s transplantation and realization.更多还原
