As progress in technology is predicted to make quantum computers available in the next few decades, it is imperative to design public-key cryptosystems capable of resisting attacks that are perceived to be possible using these new platforms. Lattice-based cryptography is one of the most promising quantum-safe candidates being considered to replace current public-key systems. Thus, it has been extensively...
In this paper, a modified CORIDC algorithm for computation of arctangent is presented. Unlike the conventional CORDIC algorithm which has constant number of iterations, the proposed algorithm calculates the nearest predefined angle to the input phase at the beginning of every iteration and then rotates by an optimal angle. As it has variable iterations, the novel rotation strategy provides faster...
In this work we propose and analyze a possible hardware architecture for experimentation on fine-grained reconfigurable supercomputing based on modern Field Programmable Gate Array (FPGA) technology. It is proposed a scalable cubic array of elementary computational units which are interconnected according to a tridimensional toroidal mesh network. Each computational unit is essentially formed by an...
Electrophysiology has recently evolved into an interactive, high-throughput endeavor. Recording from dozens to hundreds of electrodes is today routine; novel means of manipulating the system in real time, through electrical stimulation, optogenetics or sensory manipulation are allowing us to decipher neural circuit function at an unparalleled rate. To contribute to the wide dissemination of such techniques,...
This work presents the development of a remote laboratory service and its application during the teaching of Control Systems subject of third course in a Telecommunication Technology and Service Engineering degree. The application was successful allowing the student to control the same components as remotely, in a similar way as they were in the laboratory. There was an elevated interest by the students,...
This paper introduces an FPGA-based scheme to accelerate mpiBLAST, which is a parallel sequence alignment algorithm for computational biology. Recent rapidly growing biological databases for sequence alignment require high-throughput storage and network rather than computing speed. Our scheme utilizes a specialized hardware configured on an FPGA-board which connects flash storage and other FPGA-boards...
To satisfy more and more complicated requirements on information recording, processing, exchange etc. in newly developed intelligent satellites, a distributed storage system is designed based on SpaceWire network in satellite platform. In this distributed storage system, a SpaceWire router unit serving as the core device of star network connects several nodes, including onboard computers, namely,...
The “bring your own experiment” movement is being incorporated in universities all over the world. This movement is centered on students purchasing low cost hardware for use in their courses. This paper discusses the inclusion of the Basys-3 FPGA Trainer available through Digilent in a lecture only, sophomore year, Digital Logic Fundamentals course. The enhancements to this course also include the...
This paper puts forward the design of non-similar dual-redundant electromechanical actuation system for UAV landing gear, in which the main redundancy adopts multi-motor control center with digital signal processor (DSP) and field programmable gate array (FPGA) as its core algorithm, and the slave redundancy uses logic circuit to realize open-loop speed control. Due to the low real-time demanding...
In this paper, an approach is made to design a Thermal and Power efficient RAM for that reason we have used DDR4L memory and six different members of SSTL I/Os standards on 28nm technology. Every spacecraft requires most energy efficient electronic system and for that very purpose we have designed the most energy efficient RAM. In this design, we have taken two main parameters for analysis that is...
In order to comprehensively evaluate and improve the performance of the Rogowski coil electronic current transformer (RCECT), this paper presents a method for steady state characteristic and the dynamic characteristic test. The testing scenario is configured in an electromagnetic transient simulation software (PSCAD), then the digital signals are reproduced as analog signals by amplifiers. The sensor...
A data acquisition system (DAQ) is an electronic system that collects, stores and distributes information for further processing. This paper put together various DDR techniques for synchronized digital data acquisition algorithms and realization with Field Programmable Gate Array (FPGA). The proposed techniques uses Double data rate for high speed data acquisition where data capturing device is source...
A continuous real-time data acquisition and communication equipment based on Advanced RISC Machine and Field Programmable Gate Array is designed and developed, on the basis of which an on-line monitoring and fault diagnosis system for high voltage circuit breaker is realized. Mechanical, electrical and environmental parameters of the switching process can be gathered by this system. The function modules...
Segment display is very important in displaying numeric data. Although matrix display can be used to show any number with better font but it has some major disadvantages compared to segment display. Matrix display uses scanning techniques to show something, this technique is complex to implement and needs more memory. Here, a 20-segment display is proposed which can show numbers and mathematical symbols...
Anti-Tank Guided Missile (ATGM) is Indonesian Army' main defense equipment, whose availability depends on purchasing from abroad. The dependency to other countries allows many weak points and makes Indonesia merely a user, which cannot do anything against the import of defense equipment. Moreover, as a user having obligation to report the status of the defense equipment to the producer, Indonesia's...
The embedded high-speed and real-time signal processing systems are used widely in communication, navigation, sensing, measurement and control, etc. However, a high-bandwidth and high-flexibility remote communication interface is important when it comes to scenarios such as the mass data exchange between industrial computers and embedded systems. The 10Gigabit Ethernet (10GE) has been widely used...
In recent years, the RapidSmith CAD tool [1] has been used with ISE to create custom CAD tools targeting Xilinx FPGAs. This tool flow was based on the Xilinx Design Language (XDL), a human-readable representation of a netlist that contains placement and routing information. The XDL interface also provided device representation files (XDLRC files), detailing the available resources of a given FPGA...
Heterogeneous computing has recently emerged as a way to circumvent the physical and technological limitations in the design of computing devices. The pressure exerted by the ever-growing demand of increased performances has eventually made the long-awaited dream of having a traditional CPU paired up with an FPGA a reality [1], [2]. FPGAs have proven indeed to be a viable solution for energy efficient...
VLBI (Very Long Baseline Interferometry) is an important radio astronomy technology, is widely used in deep-space probers high-precision measurement. The correlator as the core data pre-processing equipment of VLBI, its performance is very important. In Chang'E mission, VLBI data playback and process just 256 Mbps in real-time before. Now the more quickly, precision, and more stations be need in next...
➔ The incremental step of LiveSynth reduces synthesis time by about 95% for incremental changes. ➔ LiveSynth shifts the paradigm to small, incremental changes and more iterations per day. ➔ We advocate for an interactive synthesis flow as a way to boost design productivity.
