Development Of Wireless Communication Platform And Design Of USB Driver Based On ARM

With the development of computer technology, embedded system, being thecenter of interest in the rising research in recent years, has been becoming animportant component in this field. As a high-performance, cost-effective RISCprocessor, the 16/32-bit RISC ARM9TDMI developed by Advanced RISC Machines,Ltd has been included in Samsung's S3C2410X combined with many importantperipheral functions, such as ethernet controller, GPIO, etc, and therefore is an idealsolution for Ethernet-based embedded systems. In this dissertation, an ARM-Linuxbased embedded product platform is proposed, designed, realized as well asembedding a simplified Linux operating system in it. This system makes use of itspriorities of high-performance, cost-effective, low-cost,to extend its GPIO, to supplygreat convenience for its later developing.The software is based on Linux, which has been widely applied in embeddedsystems because of its significant advantages, such as open codes and powerfulnetwork support, etc. The hardware and software introduced in this paper form aproduct platform, which has been ready for future applications.As a kind of bus technology, USB has been applied in more and more fields.This dissertation realizes the design of USB drivers under Linux operating system.Furthermore, it combines with mobile communicating technology to realize todevelop the wireless communicating platform.The main work of this dissertation could therefore be summarized as follows:1) Learned the domestic and international current situation and development ofembedded system. This dissertation introduces the hardware structure, operatingsystem and developing flow of the processor based on ARM-9.2) Researched the transplantation of Linux on ARM-9 hardware platform. Itincludes building the transplantation environment, making Bootloader, reducing andtransplanting Linux, making root files, and so on.3) Developed the USB drivers under Linux operating system. It includes hostUSB drivers and slave USB drivers. 4) Combined the mobile communication technology with embedded system, tomake use of its high performance-price ratio, abundant functions and interfaces,strong extendings based on the ARM-9 processor, realizing developing the wirelesscommunication platform.
