Development of the Reconfigurable Host-Based IPS Processor with the Multiplexed Data Bus

可重新配置的基于主机的IPS处理器是为高度准确地检测智能手机或电池操作的个人电脑中的未经授权的计算机访问而开发的。该处理器由MAC单元、防火墙逻辑单元和CPU组成。每个单元都与一条总线相连，以传输以太网帧。也就是说，需要大量的布线。在本研究中，多工汇流排是利用波管线技术来开发，目的是为了达成高效率的封包转送。评估总线，并确认总线的多路复用操作。此外，对处理器中所需CPU的性能进行了评估，并增强了处理器中无线LAN的密码强度。

The Reconfigurable Host-Based IPS Processor is developed for a highly accurate detection of unauthorized computer access in a smartphone or a personal computer with battery operation. The processor is composed of MAC Unit, Firewall Logic Unit with LUTs for Intrusion Prevention and a CPU. Each unit is connected with a bus to carry Ethernet frames. That is, a huge number of wiring is required. In this study, a multiplexed bus is developed by using wave-pipeline technique aiming at a highly effective packet forwarding. The bus is evaluated, and the multiplexing operation of the bus is confirmed. In addition, the performance of the CPU needed in the processor is evaluated and cipher strength of the wireless LAN in the processor is strengthened.
