Design And Implement The Embedded Digital Home System Based On Blackfin DSP

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.
