In order to break through the transmission capacity limitation of airborne computers, an airborne communication computer based on PowerPC+ SRIO Architecture is designed according to the wide application of the SRIO bus and the high performance of the PowerPC processor. In terms of optimization design, the computer adopts a redundant fault-tolerant system and improves the SRIO register initialization and address mapping method. The experimental results show that the transmission speed of the airborne communication computer based on PowerPC+ SRIO architecture reaches 81% of the theoretical value, and 16KBytes data can be transmitted in real time within 1μs.
