| With the rapid development of both information technology and Internet, and theirintegration, the TV that is simply used to watch television program by satellite antenna inthe past, now it has been given a new definition: Smart TV. The Routon ElectronicCompany is entirely optimistic about the prospects of smart TV, and catches the chance toresearch their own Smart TV system. It uses the latest Intel Atom CE4100processor as thehardware platform and uses the Linux2.6.28kernel open source operating system to buildthe Smart TV system. This paper studies the key technology of transplant the Smart TVsoftware system to the new generation of digital home chip "Atom" CE4100.First, have a good knowledge about the whole software embed system and thearchitecture of processer. then build development environment, including the compiler, it isused to compile small application and the kernel, and the integrated developingenvironment based on the “meihua” operating system, using compile big project.Then, transplant the kernel and build the root file-system, mainly including modifyingthe related kernel code, cutting kernel, modifying the scripts according to the request ofsystem platform, cutting root file-system.After transplant the kernel and completing building the root file-system transplant thedriver and protocol. Paper mainly narrates the transplantation of infrared remote controllerand wireless share technology of Airplay protocol.Last, the development of system tools. Mainly implement single-board test tool to testthe main-board of Smart TV and infrared remote controller, and develop the burn tools.After the work about transplanting the Smart TV system to the mainboard, the systemservices and application can run on it stably. |
