On the financial side, a key factor for the success of a smart-city initiative is the low cost of the sensors. On the technical side, the units need to be flexible enough to cover different roles, and to be reconfigurable for a distinct target. The capability to interact with an already deployed infrastructure, like a preexistent web-server, is a favorable feature from both the financial and technical...
Due to severe power and timing constraints of the "things" in the Internet of things (IoT), cryptography is expensive for these devices. Custom hardware provides a viable solution. However, implementations of cryptographic algorithms in the devices need to be upgraded frequently compared to the longevity of these "things". Therefore, there is a critical need for reconfigurable,...
This paper introduces a newly developed Object-Oriented Open Software Architecture designed for supporting security applications, while leveraging on the capabilities offered by dedicated Open Hardware devices. Specifically, we target the SEcube™ platform, an Open Hardware security platform based on a 3D SiP (System on Package) designed and produced by Blu5 Group. The platform integrates three components...
High Performance Computing (HPC) Systems are usually large systems which require specialized infrastructure. For a variety of small time users, who need performance of the parallel computing for their applications, such systems are unaffordable and inaccessible for a number of reasons. Even to setup a small state-of-the-art HPC system, such users would require vast efforts and expertise to design...
Due to the high cost and high power consumption problem of the present smart home server, we designed and implemented a home server based on embedded system, mainly developed by ARM11 for a hardware platform, Linux system for operating system, SQLite database and BOA server for a software platform. The home server has successfully implemented the network communication, SQLite database peration and...
Inter-vehicle communication (IVC) is a key component enabling the autonomous driving vehicles. Standardization of IVC is advanced but yet improvements are still introduced. Congestion control is one of the sensitive topics. The IVC European standard ITS-G5 addresses the congestion issue enabled by a geo-networking protocol that exploits at networking level the geographic information. Implementation...
As the most active project in the Hadoop ecosystem these days (Zaharia, 2014), Spark is a fast and general purpose engine for large-scale data processing. Thanks to its advanced Directed Acyclic Graph (DAG) execution engine and in-memory computing mechanism, Spark runs programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk (Apache, 2016). However, Spark performance is impacted...
Creating quick and dirty prototypes is a simple and effective way to demonstrate the feasibility of new ideas in network research. Though, small scale proof-of-concepts may lack the performance needed to apply them to real world test cases. Thanks to powerful packet processing frameworks such as netmap and DPDK, high-performance packet forwarding systems can be implemented in software today.We present...
Driven by the increasing diversity of current and future HPC hardware and software platforms, the HPC community has seen a dramatic increase in research and development efforts into the composability of discrete software systems. While modularity is often desirable from a software engineering, quality assurance, and maintainability perspective, the barriers between software components often hide optimization...
Accelerating relational databases in general and SQL in particular has become an important topic given thechallenges arising from large data collections and increasinglycomplex workloads. Most existing work, however, has beenfocused on either accelerating a single operator (e.g., a join) orin data reduction along the data path (e.g., from disk to CPU). In this paper we focus instead on the system...
Due to the advent of active safety features and automated driving capabilities, the complexity of embedded computing systems within automobiles continues to increase. Such advanced driver assistance systems (ADAS) are inherently safetycritical and must tolerate failures in any subsystem. However, fault-tolerance in safety-critical systems has been traditionally supported by hardware replication, which...
In this paper we demonstrate the power and flexibility of extreme model-driven design using C-IME, our integrated modelling environment for C/C++ by showing how easily an application modelled in C-IME can be enhanced with hardware security features. In fact, our approach does not require any changes of the application model. Rather, C-IME provides a dedicated modelling language for code generators...
The chance to influence the lives of a million children does not come often. Through a partnership between the BBC and several technology companies, a small instructional computing device called the BBC micro:bit will be given to a million children in the UK in 2016. Moreover, using the micro:bit will be part of the CS curriculum. We describe how Microsoft's Touch Develop programming platform works...
Wireless Sensor Networks (WSNs) have evolved during the last decade, becoming an accessible technology in the market nowadays. Even cutting edge state of the art works are still being carried out in universities and research centers and departments, the curriculum of communication, computer science and electronic engineers lacks of contents related to specific disciplines inherent to WSNs field. The...
In this paper, image processing algorithms designed in Zynq SoC using the Vivado HLS tool are presented and compared with hand-coded designs. In Vivado HLS, the designer has the opportunity to employ libraries similar to OpenCV, a library that is well-known and wide used by software designers. The algorithms are compared in terms of area resources in two conditions: using the libraries and not using...
In order to compare and rank the worlds fastest computers, benchmarks evaluating their performance are required. A single execution of HPL is used for the most widely recognized ranking: the TOP500. Lately, two benchmarks, arguably more representative of typical modern workloads, have been proposed: HPCG and HPGMG. Currently, all three benchmarks use the highest observed performance from a single...
A brief review of Protected Execution Mode (PEM) for user-space applications featured in Elbrus architecture is described first. Then, AddressSanitizer, a well-known utility by Google Inc, is considered as an example of a pure software technique of memory control. Comparative analysis of these solutions is given with performance flaws, applicability and boundary violation detection quality.
Commercialization of desktop milling machines has made rapid Printed Circuit Board (PCB) fabrication accessible. Unfortunately, PCB design for embedded and robotic systems is still a tedious and time consuming activity. In this paper, we present a technique, Just In Time Printed Circuit Board (JITPCB) for designing PCB systems at speeds commensurate with the capability of desktop PCB milling machines...
Energy efficiency can have a significant influence on user experience of mobile devices such as smartphones and tablets. Although energy is consumed by hardware, software optimization plays an important role in saving energy, and thus software developers have to participate in the optimization process. The source code is the interface between the developer and hardware resources. In this paper, we...
The common DPU platform for ESA JUICE mission instruments is a hardware and software platform developed by Cobham Gaisler for the scientific instrument payloads of the European Space Agency Jupiter Icy Moons spacecraft. The hardware is based around the GR712RC dual-core LEON3-FT processor with GRSPW2 SpaceWire interfaces. To accompany the JUICE instrument hardware, a flight quality SpaceWire software...
