Yusuf S, Luk W, 2005, Bitwise optimised cam for network intrusion detection systems, Pages: 444-449

String pattern matching is a computationally expensive task, and when implemented in hardware, it can consume a large amount of resources for processing and storage. This paper presents a novel technique, based on a tree-based content addressable memory structure, for a pattern matching engine for use in a hardware-based network intrusion detection system. This technique involves hardware sharing at bit level in order to exploit powerful logic optimisations for multiple strings represented as a boolean expression. Our approach has been used to implement the entire SNORT rule set with around 12% of the area on a Xilinx XC2V8000 FPGA. The design can run at a rate of approximately 2.5 Gigabits per second, and is approximately 30% smaller in area when compared with published results. The performance of our design can be improved further by having multiple designs operating in parallel. © 2005 IEEE.

Styles H, Luk W, 2005, Compilation and management of phase-optimized reconfigurable systems, Pages: 311-316

A program phase is an interval over which the working set of the program remains more or less constant. This paper presents a dynamic optimization scheme which uses program phase information to optimize designs for reconfigurable computing. We present a mathematical formulation of the optimization problem and propose a solution which comprises of : (1) A hardware compilation scheme for generating configurations that are specialized for different phases of execution. (2) A runtime system which manages interchange of these configurations to maintain specialization between phase transitions. We report experimental results for Xilinx Virtex FPGAs involving OpenGL SPECview-perf benchmarks and demonstrate 95.39% speedup over an optimized uniform rate static design and 11.13% speedup over an optimized multi-initiation interval static design. We present a framework for a posteriori performance analysis and architectural exploration with which we (a) establish a performance upper bound under perfect phase optimization, (b) investigate sensitivity to reconfiguration time, (c) examine the quality of the proposed algorithm for phase-detection. The optimization is shown to be surprisingly insensitive to increased reconfiguration time. Faster reconfiguration yields limited benefits and performance improvements are possible upto 1 second reconfiguration time. © 2005 IEEE.
