This paper describes a Cuckoo-based Pattern Matching (CPM) engine based on a recently developed hashing algorithm called Cuckoo Hashing. We implement the improved parallel Cuckoo Hashing suitable for hardware-based multi-pattern matching with arbitrary length. CPM can rapidly update the static pattern set without reconfiguration while consuming the lowest amount of hardware. With the power of massively...
Digital cellular mobile technologies have been rapidly developed since the analog technology was presented. This has led to many new applications especially multimedia. More interestingly, the new mobile has embedded the digital camera in itself, so that the user can take photos, record the videos and make video calls. Although many applications of mobile uplink video exist, we cannot see the video...
Most compiler optimization techniques concern most about speed. In this paper, we present two high-level memory optimization methods for ARM-based secure applications on mobile phones, pocket PCs, etc. The experiments using RSA encryption on ARM920T with 1024-bit random public keys show that the proposed techniques can complement the existing speed-oriented ones to achieve less number of memory accesses,...
Pattern matching for network intrusion/prevention detection requires extremely high throughput with frequent updates to support new attack patterns. Most of current hardware implementations have outstanding performance over software implementations. However, the requirement for dynamic update pattern set is still challenging for hardware researchers. This paper describes a novel FPGA-based pattern...
ClustalW is the most widely used tool for aligning multiple protein or nucleotide sequences. The alignment is achieved via three stages: pairwise alignment, guide tree generation and progressive alignment. This paper analyzes and enhances a multithreaded implementation of ClustalW called ClustalW-SMP for higher throughput. Our goal is to maximize the degree of parallelism on multithreading ClustalW...
Most compiler optimization techniques concern most about speed. In this paper, we present two high-level power/energy optimization methods for ARM-based battery-powered embedded multimedia systems, e.g. mobile phones, pocket PCs, personal multimedia systems, etc. The experiments using MPEG-4 simple profile level 0 (SP@L0) video decoder on ARM920T with two QCIF video sequences 15 fps, 24 kbps show...

Recently, FPGAs (field programmable gate arrays) technology have made significant advances in both speed and capacity. Millions of logic gates are now available for reconfiguration programming. To fully exploit the potential of so many programmable devices, powerful design methodology must be developed. In this paper, we propose a novel systematic computer-aided design methodology that can efficiently...
