Design and Implementation of Embedded Residential Gateway and TCP/IP Based on Uc/os-II

摘要

This paper will introduce the design and function implementation of each module of the residential gateway. First, it explains respectively the light weight GUI and the TCP/IP based on software, which includes the design thought, structure and implementation of the kernel; Then will introduce how to port the GUI and TCP/IP to the real time operation system (μC/OS-II) and ARM microprocessor device and how to design the device drivers. This paper elaborate the design and Implementation of a minimal emIP TCP/IP stack, and it expatiate on the arithmetic and the data structure used for the implementation of protocol and related sub-system. Finally, it explains the design thought and work process of how to communicate with the outer and how to manage the intelligent wiring using the gateway.
