1 An Efcient I/O Architecture for RAM-based Content

content-addressable-memory (RAM-based CAM) always suffers high latency. Two primary causes of such latency include:(1) the compulsory erasing stage along with the writing stage and (2) the major difference in data width between the RAM-based CAM (e.g., 8-bit width) and the modern systems (e

A Dynamically Reconfigured Multi-FPGA Network Platform

For extending the NetStage-based MalCoBox to multiple devices, a unidirectional ring suffices (Figure 4). The unidirectional ring needs fewer I/O pins on the FPGAs and avoids the increased latency of the bus-turnaround cycles that would be required when running a bidirectional bus over the same pins.

Face Recognition with Hybrid Efficient Convolution

For Winograd-based convolution with larger kernels, we evalu-ate F(2 ×2,5 ×5), and F(2 ×2,7 ×7). For our implementation of FFT-based convolution, since the Radix-2 FFT inputs must be of size of powers of 2, we choose the padding to make up size 8, 16, and 32, for input size 6, 12, and 24 respectively.

Grouping Methods for Pattern Matching in Probabilistic

Apr 20, 2015 · Pattern matching is used to find complex events in data streams. In probabilistic data streams, however, the system may find multiple matches in a given time interval. This may result in inappropriate matches, because multiple matches may correspond to a single event. High performance FPGA and GPU complex pattern In [34] an NFA implementation of regular eions on FPGAs is described. A pattern matching approach, built on GPU-based NFA regular eion engine is reported in [5].

High performance FPGA and GPU complex pattern matching

Aug 26, 2014 · The wide and increasing availability of collected data in the form of trajectories has led to research advances in behavioral aspects of the monitored subjects (e.g., wild animals, people, and vehicles). Using trajectory data harvested by devices, such as GPS, RFID and mobile devices, complex pattern queries can be posed to select trajectories based on specific events of interest. LLVM-based automation of memory decoupling for OpenCL Feb 01, 2020 · Despite the significant potential, OpenCL for FPGAs introduces a set of new design challenges. Throughput-oriented platforms (e.g., GPUs) often rely on built-in schedulers to manage concurrent thread 1 execution at massive scale (over many cores) thus hiding memory latency. In contrast, FPGAs efficiency stems from a customized data-path, operation-level parallelism and also

Regular Eion Matching Can Be Simple And Fast

Two regular eions can be alternated or concatenated to form a new regular eion:if e 1 matches s and e 2 matches t, then e 1 |e 2 matches s or t, and e 1 e 2 matches st. The metacharacters * , + , and ? are repetition operators:e 1 * matches a sequence of zero or more (possibly different) strings, each of which match e 1 ; e 1 Revisiting Multiple Pattern Matching Algorithms for Multi Sep 23, 2011 · Due to the huge size of patterns to be searched, multiple pattern searching remains a challenge to several newly-arising applications like network intrusion detection. In this paper, we present an attempt to design efficient multiple pattern searching algorithms on multi-core architectures. We observe an important feature which indicates that the multiple pattern matching time mainly depends

SDFA:Series DFA for Memory-Efficient Regular Eion

Jul 17, 2012 · Abstract. Regular eion (RegEx) matching plays an important role in various network, security and database applications. Deterministic finite automata (DFA) is the preferred representation to achieve online RegEx matching in backbone networks, because of its one single pass over inputs for multiple RegExes and guaranteed performance of O(1) memory bandwidth per symbol.
