This paper describes the design and implementation of SD card driver and tiny file system for multi-process micro-kernel embedded operating system on ARM in technical details, including structure of device driver, key techniques of designing SD card driver, architecture of the tiny file system, a brief description of its designing and a demo example. The SD card driver and tiny FS are implemented with GNU tool chain by the author of this paper. Practice proves that the system can be used for not only embedded application developments but also related curriculum teaching.

Inter Process Communication

This paper describes the design and implementation of piping functionality for ARM based multi-process mono-kernel embedded operating system, including overview of inter-process communication, key techniques of designing piping routines such as getting i-node for piping, creating pipe, reading and writing pipe, and terminating pipe, etc. At the final, the paper provides a demo example to show the effect. Based on the piping routines described in this paper, more powerful shell interpreter with redirecting and piping functionalities as well as other shell commands analogous to that of embedded Linux can be implemented.

Linux Platform

This paper describes the design and implementation of Web based secure embedded system, including tiny secure Web server, embedded system-based CGI library, and utilities for security, such as CAPTCHA program and mail sending program. The entire system is designed in C by the author of this paper on Linux platform with GNU tool chain. A Web based secure embedded application demo system is also designed to show the architecture and running effect. On the premise of implementing essential functions, the scale of the system is designed as small as possible therefore it is suitable not only for embedded Linux development on Web based applications but also for embedded system course teaching in colleges and universities. By some further extensions, it can also be used on development of general Web based MIS.
