Abstract

Multi-pattern matching refers to the search for multiple patterns in a given text at the same time. This matching on FPGA is expected to scale with the number of patterns in hardware consumption. In this paper, we propose a matching architecture that compares the prefixes of multiple patterns with the prefix of the matching window in parallel. The comparison will continue with the body of each pattern if the corresponding prefix is matched. This architecture is called the prefix-based multi-pattern matching architecture. Our implementation on FPGA shows that the proposed matching architecture achieves much higher performance than the implementation on CPU, while the hardware cost is low.
基于前缀的FPGA多模式匹配
多模式匹配是指在给定文本中同时搜索多个模式。FPGA上的这种匹配预计将随着硬件消耗的模式数量而扩展。在本文中,我们提出了一种匹配架构,将多个模式的前缀与匹配窗口的前缀并行比较。如果匹配到相应的前缀,将继续对每个模式的主体进行比较。这种体系结构称为基于前缀的多模式匹配体系结构。我们在FPGA上的实现表明,所提出的匹配架构比在CPU上实现的性能要高得多,而且硬件成本低。
