Traditional processor design approaches using CISC and RISC philosophies suffer from low performance. One of alternative approaches to improve system performance is instruction level parallelism (ILP). Among the processor architectures supporting ILP, very long instruction word (VLIW) processors offer some advantages such as low power consumption and hardware complexity. In this paper, we introduce...
Perl Compatible Regular Expression (PCRE) is increasingly used in Network Intrusion Detection System due to its efficiency. However, there are many issues that have not been completely solved for PCRE matching on hardware platform. In this paper, we propose an FPGA-based PCRE matching architecture that effectively improves the constraint repetition, an importance feature of PCRE. We enhance our architecture...
Asynchronous circuits are more and more predominant because their advantages in comparison with synchronous circuits. While asynchronous circuits can be implemented in custom VLSI, their fabricated-time is too long to allow rapid prototyping. Meanwhile, FPGA devices are dominant implementation media for digital circuits. Unfortunately, they do not support asynchronous circuits because of the lack...
