Abstract
This paper analyzes the requirements of the real time communication under Xenomai platform. It presents an Ethernet-based real time communication solution. It ports the Ethernet Network Interface Card(NIC) driver from the Linux kernel to the real time kernel. Time Divide Multiple Access(TDMA) based Media Access Control(MAC) supplies a definite period of time sending data frames for all nodes. It uses demultiplexing method to solve the priority inversions of threads and data packets, and also uses zero-copy technology to reduce the times when data packets cross the protocol stack. Experimental results show that this solution can realize the real time communication of inter task under Xenomai platform.关键词
