%X A network firewall system based on Godson2E CPU was designed. This solution used Godson processor as the CPU and a self-designed north bridge. The key technologies of the design such as firewall software strategy, hardware architecture design, signal integrity and the solution of testing the network packet passed ratio and delay were discussed and the corresponding solutions were given too. In order to solve the signal integrity problem, a layout mechanism of restriction in advance and simulation subsequently was put forward, which improved the design reliability of the motherboard with high-speed signals. A testing and computing solution for the network packet passed ratio and delay was also given, which was the key performance parameters of the network firewall computer system. Theoretical and experimental results show that this solution is an all-purpose, secure and reliable firewall system design.
