We propose an autonomous wireless device with e-paper display and low-energy communication for information requirements in personal environments. A commercial hardware platform is used and an additional PCB designed to achieve a power saving strategy. To detect existing devices and transmit images a distributor node is defined and implemented.
Post-silicon validation deals with detection and diagnosis of errors that, due to existing limitations in pre-silicon verification, escape to the silicon prototypes and need to be fixed before committing to high-volume manufacturing. Electrical errors, such as those caused by cross-talk or power droops, are particularly difficult to catch during the pre-silicon phase because of the insufficient accuracy...
Embedded systems have an increasing importance in our everyday lives. The growing complexity of embedded systems and the emerging trend to interconnections between them lead to new challenges. Intelligent solutions are necessary to overcome these challenges and to provide reliable and secure systems to the customer under a strict time and financial budget. WISES 2015 is a platform for presentation...
Overview. Today, most commercially available 3D display systems require the viewers to wear some sort of shutter-or polarization glasses, which is often regarded as inconvenience. Ideally, a 3D display system should not require the users to wear additional gear. In fact, the optimum would be a display that replicates the original light-field of a scene. So-called multiview aütostereoscopic displays...
In this paper, we propose a method to optimize two-layer light field display using depth initialization. In contrast to existing trade-off work between performance and processing time, this paper firstly models the display principle of layered light field display, and then performs layered initialization with the prior known depth of 3D objects, and finally optimizes the layered images for light field...
This paper presents the performance comparison of boost and interleaved boost converter for Maximum Power Point Tracking (MPPT). First simulation study is done on PSIM platform and then hardware prototype of interleaved boost converter (IBC) and conventional boost converter (CBC) with the embedded MPPT controller has been developed. Incremental conductance (INC) MPPT algorithm has been used to track...
This paper describes the co-simulation methodology adopted for hardware verification of a next generation network packet processing engine (Advanced I/O Processor or AIOP) utilizing virtual prototype models developed originally for software verification. Though co-simulation strategies are common in verification of stand-alone processors, they have seldom been used for mega-modules and SoC, which...
This paper presents a demo system that realistically displays the glasses-free light field 3D effect with a triple-layer structure. By combining multi-layer panels, high refresh rates, and directional backlighting together, we achieve a wide field of view and large depth of field with a thin form factor. Additionally, using some off-the-shelf hardware, this system demonstrates an interesting light...
Post-silicon validation is becoming widely adopted because it runs significantly faster than pre-silicon verification and hence it helps uncover subtle design errors that escape to silicon prototypes. However, it is hindered by limited controllability and observability, which makes it challenging to reuse pre-silicon content. In order to enable the reuse of stimuli constraints from pre-silicon verification...
This paper presents a 25kW six-level Modular Multilevel Converter prototype. The designed prototype is an industrial power converter that can be used by the industry. The converter is shown together with a high-performance hardware platform control designed for large multilevel converters. The hardware platform is a custom platform based on Zynq-7000 System-On-Chip that provides high processing performance...
In recent years, Network Function Virtualization (NFV) has gained a lot of traction from both industry and academia. NFV promotes vendor-independence and rapid evolution through open source software, open standards, and open APIs. However, adopting these principles for virtual middleboxes or Virtual Network Functions (VNFs) is not enough. The VNF orchestration systems also need to adopt the same principles,...
Wearable devices have emerging in last years with diverse applications for provide user convenience. Health care, sports, safety are some examples of areas in which wearable devices have been applied. This paper describes an overview about wearable architectures found in the literature and presents a novel wearable for monitoring ecological environments. The wearable is composed of a Head-UP Display...
The 2010 Joint Space Communication Layer (JSCL) Initial Capabilities Document (ICD) forecasts a large demand increase for US MILSATCOM in contested environments during the 2020–2025 timeframe. In response, the US Air Force in 2012 commenced the MILSATCOM Design for Affordability Risk Reduction (DFARR) effort to develop prototypes for a new protected tactical communications system. MIT Lincoln Laboratory...
The Academic Network of Uruguay (in spanish Red Académica Uruguaya - RAU) comprises several universities, research centres and government institutions. RAU is planning a major upgrade, and Software Defined Networking (SDN) is being evaluated as a technology which may promote the deployment of improved network services, while allowing researchers to keep on investigating over the operational network...
As interdisciplinary sciences getting popular with every passing day, the need of electronic devices interfacing with a PC is also increasing. Very useful products (Arduino, RasberryPi, etc) made their way in commercial market to cater such needs however they require programming skills, specific IDE's (integrated development environments) and lack compatibility with useful tools such as NI (National...
Engineering students need to learn highly effective processes for pursuing difficult design problems that require highly innovative solutions. Few studies exist of highly successful expert design teams. The current paper presents the results from a multi-million dollar department of energy research project which reduced the racking hardware and mounting installation costs for commercial applications...
Designing hardware specialized for a target application domain dramatically improves energy efficiency. However, the design of specialized hardware is hampered by high cost, dominated by the effort needed to design, validate, and verify the custom integrated circuit. An agile design approach, discussed here, relies on hardware generators coupled with rapid design of iterative prototypes and open source...
The paper focuses on the problem of interconnecting different cloud providers with the aim of offering enhanced services. The Intercloud scenario is based on the key concept that any cloud by itself does not have infinite natural resources or stable geographic location. The paper presents a distributed architecture for interconnecting existing cloud services, from different cloud providers (Firebase,...
The objective of post-silicon validation is to detect design errors on early silicon prototypes. Electrically-induced errors commonly manifest as bit-flips in the logic domain and they occur under unique operating conditions, which are often not-easily-repeatable. In order to shorten the long detection latencies from an error's manifestation until its observation (i.e. system crash), embedded assertion...
The increase of luminosity at High Luminosity LHC will require the introduction of tracker information at Level-1 trigger system for the experiments to maintain an acceptable trigger rate to select interesting events despite the one order of magnitude increase in the minimum bias interactions. To extract in the required latency the track information a dedicated hardware has to be used. We present...
