A novel improved method for real-time parallel computer system based on StarFabric is proposed. Considering the shortcoming of traditional host bus in avionics environment, this paper suggests a novel method integrating switch bus to improve avionic environment network. This makes a breakthrough in essential technology such as system architecture and the realization of node computer, design methodology of high speed real-time bus and system fault redundant software, constructs a principle distributed computer system with Pentium processor and MPC8245, a PowerPC processor, which has fault redundant and parallel computing capability, high speed data transmit capability, and performs high speed real-time computing.
