Drowning of water vehicles frequently occur during the rainy seasons. Several reasons exist behind such drowning. Among them, swing for the brutal current is mentionable. If there would be a technique, which can raise an alarm after reaching a risky level of swing during the brutal current, then the drivers as well as the passengers of the water vehicle can be alert and prepare for necessary actions...
To handle the stringent performance requirements of future exascale-class applications, High Performance Computing (HPC) systems need ultra-efficient heterogeneous compute nodes. To reduce power and increase performance, such compute nodes will require hardware accelerators with a high degree of specialization. Ideally, dynamic reconfiguration will be an intrinsic feature, so that specific HPC application...

The use of reconfigurable FPGA devices to support the execution of computationally intensive software tasks is discussed in this paper. A system architecture consisting of multiple serially-connected FPGAs is developed, where each FPGA holds a pool of reconfigurable regions. An accelerator can be reconfigured into a region, replaced or discarded at runtime. Configurable connection blocks are responsible...
In recent years, network intrusion detection systems (NIDS) have faced a serious throughput challenge as a result of the rapid increase of network links to 1 and 10 Gbps rates. Consequently, this calls for NIDS to have wire-speed packet processing and real-time detection of malicious traffic. Snort is the most popular NIDS. Snort is an open source software-based NIDS and runs as a single threaded...
Network's speed continues to increase at a high rate resulting in massive network traffic. This results in a need to have a high-speed network intrusion detection system (NIDS) to detect malicious traffic. Snort is a software-based NIDS that can run as a single threaded application. However, it may not be able to detect intrusions in real-time especially in networks with high traffic. This paper proposes...
In LTE base-stations, RoHC is a processing-intensive algorithm that may limit the system from serving a large number of users when it is used to compress the VoIP packets of mobile traffic. In this paper, a hardware-software and a full-hardware solution are proposed to accelerate the RoHC compression algorithm in LTE base-stations and enhance the system throughput and capacity. Results for both solutions...
Multicore architectures, especially hardware accelerator systems with heterogeneous processing elements, are being increasingly used due to the increasing processing demand of modern digital systems. However, data communication in multicore architectures is one of the main performance bottle-necks. Therefore, reducing data communication overhead is an important method to improve the speed-up of such...
In this paper, we present an efficient and high performance linear recursive variable expansion (RVE) implementation of the Smith-Waterman (S-W) algorithm and compare it with a traditional linear systolic array implementation. The results demonstrate that the linear RVE implementation performs up to 2.33 times better than the traditional linear systolic array implementation, at the cost of utilizing...
In this paper we adapted a novel approach for accelerating the Smith-Waterman (S-W) algorithm using Recursive Variable Expansion (RVE), which exposes extra parallelism in the algorithm, as compared to any other technique. The results demonstrate that applying the recursive variable expansion technique speeds up the performance by a factor of 1.36 to 1.41, as compared to traditional acceleration approaches...
