A Real-Time Kernel for Embedded Internet Applications

A real-time operating system kernel EIRTK with micro-kernel architecture is presented to meet the demands of developing the Internet applications in embedded systems. EIRTK is designed to be a multi-task preemptive kernel based on priority. Task scheduling, synchronization and communication between tasks, timer management, network protocol and other system services are realized in EIRTK to guarantee the real-time performance and reliability of the Internet applications. Partial protocols of TCP/IP suite are implemented in EIRTK to realize the embedded devices linked to the Internet. The performance experimental results of EIRTK shows that the Internet application demands for most of embedded systems can be met.
