Research and Design of Embedded Internet Technology Based on a Real-Time Kernel
基于一个实时内核的嵌入式Internet技术的研究与实现

A real-time kernel-WebitX's architecture and design scheme with microkernel architecture is proposed from the viewpoint of development Internet applications in embedded system. In order to support complicated applications under embedded Internet environment. WebitX is designed a multitask preemptive kernel based on priority. To guarantee the timeliness and reliability of embedded Internet applications.such system services as task scheduling, synchronization and communication between tasks, timer management and network protocol are provided by WebitX. An embedded TCP/IP stack is provided by WebitX to realize devices linked to Internet and partial functions of TCP/IP suite are implemented using a modular solution with the limit of hardware resource. A network interface for traditional devices is provided by this stack and accordingly efficient embedded Internet communication is achieved.
