High Level Modeling and Hardware Implementation of Image Processing Algorithms Using XSG
2019
International audience; Design of Systems-on-Chip has become very common especially with the remarkable advances in the field of high-level system modeling. In recent years, Matlab also offers a Simulink interface for the design of hardware systems. From a high-level specification, Matlab provides self-generation of HDL codes and/or FPGA configuration codes while providing other benefits of easy simulation. In addition, a large part of the Systems-on-Chip use at least one image processing algorithm and at the same time border detection is one of the most used algorithms. This paper presents a study and a hardware implementation of various algorithms of borders detection realized under Xilin…
A Novel Approach for Accelerating Bitstream Relocation in Many-core Partially Reconfigurable Applications
2013
International audience; Partial Bitstream Relocation (PBR) has been introduced in recent years, as a means to overcome the limitations of the traditional Xilinx Partial Reconfiguration flow, particularly in terms of the limited module placement, a fact that can greatly reduce the memory footprint of applications which require multiple implementations of the same module... However, PBR consumes scarce resources in hardware implementations, and introduces a prohibitive time overhead when done in software. This is particularly true in applications such as large scalable systems, which typically require multiple copies of the same module to accelerate a task, but in which the relocation time ov…
An efficient hardware implementation of Diamond Search motion estimation using CAL dataflow language
2011
Motion estimation represents a key module in video compression. The Reconfigurable Video Coding context (RVC) requires proposing a flexible solution for motion estimation. The motion estimation performance should be modified to fit with the user or the environment's constraints. Depending on the required performances fixed by the application, a full search is sometimes not suitable, hence, alternative fast/reduced solutions should be considered. In this paper, an efficient Diamond Search motion estimation, described in RVC-CAL actor language, is introduced. Starting from a high level description based CAL language, an automatic translation of the proposed CAL module to HDL is performed. Thi…
Impact of non-programmable renewable sources in Day-Ahead Market in Sicily. Reasons to make more flexible and smarter the national transmission grid.
2014
This article describes technical and market aspects that characterize the Sicilian electrical system, the non-programmable renewable sources impacts on the energy markets (Day-Ahead Market and ancillary services market) and on Sicilian system operation, to evaluate the grid integration of renewable energy sources in a future Sicilian smart grid.
Basic Concepts of Power Distribution Network Design for High-Speed Transmission
2011
This paper tries to gather the Power Distribution Network (PDN) techniques used to preserve power integrity in PCB designs when transmitting data rates over 6 Gbps using the newest commercial optical modules. The PDN design described allows for proper impedance control of the power supply with the appropriate choice of the number, location and values of capacitors. This method needs the knowledge of the electrical RLC model of the regulators, copper planes, capacitors and vias used in the PCB. A particular case of PDN design will be presented for a module using one SNAP12 optical transmitter and one receiver connected to an Altera Stratix II GX FPGA. This board is designed to work with data…
A new ATLAS muon CSC readout system with system on chip technology on ATCA platform
2015
The ATLAS muon Cathode Strip Chamber (CSC) backend readout system has been upgraded during the LHC 2013-2015 shutdown to be able to handle the higher Level-1 trigger rate of 100 kHz and the higher occupancy at Run 2 luminosity. The readout design is based on the Reconfigurable Cluster Element (RCE) concept for high bandwidth generic DAQ implemented on the Advanced Telecommunication Computing Architecture (ATCA) platform. The RCE design is based on the new System on Chip XILINX ZYNQ series with a processor-centric architecture with ARM processor embedded in FPGA fabric and high speed I/O resources together with auxiliary memories to form a versatile DAQ building block that can host applicati…
Performances of the Fault Decoupling Device when unbalanced and multiple faults occur on distribution systems.
2005
Nowadays industrial processes are largely based on electronic devices such as programmable logic controllers and adjustable speed drives. Consequently, industrial equipments became less tolerant towards power supply disturbances. Voltage dips due to faults are surely among the worst disturbances for industrial equipments. A paper machine can be affected by disturbances of only 10% voltage drop lasting for 100 ms. A voltage dip of 75% (of the nominal voltage) with a duration shorter than 100 ms results in material loss in the range of thousands of US Dollars for semiconductors industry [1].
Informācijas Tehnoloģiju iespēju izmantošana būvniecības projektu tāmēšanas pārvaldībā
2016
Būvniecības tāmju izstrādē visplašāk izmantotā lietojumprogramma ir MS Excel lietotne, kas nodrošina tāmēšanai nepieciešamo izklājlapu tabulāro formu un aprēķinu formulu veidošanu, kā arī datu kopēšanas un citu tekstuālu un skaitlisku datu apstrādes funkcionalitāti. Lai arī MS Excel programmatūra ir vispār atzīta tāmētāja darba vietas platforma, izklājlapu programmatūra ir limitēta un nesniedz visu tāmēšanas darbu pārvaldībai nepieciešamo atbalstu, ko ir iespējams nodrošināt ar informācijas tehnoloģiju risinājumiem. Lai identificētu konkrētas tāmēšanas procesa efektivizēšanas iespējas, darba ietvaros veikta būvniecības tāmju izstrādē ietverto procesu apskats un analīze, veikta izpēte par ti…
Il governo del capitale intellettuale attraverso il raccordo tra modelli contabili e di System Dynamics. Una prospettiva di programmazione e controll…
2004
Il presente scritto tenta di far luce sul tema del capitale intellettuale in una prospettiva economico-aziendale, focalizzando in particolare il concetto di governo della conoscenza aziendale. La tesi sostenuta dagli autori è che i processi inerziali di sviluppo e declino della conoscenza non devono essere astrattamente ignorati, relegando l’area Organizzazione e Sistemi al rango di centro di spesa discrezionale. Questa semplicistica prospettiva di analisi può indurre il management all’adozione di politiche miopi, che portino cioè a rinviare investimenti necessari in sviluppo della conoscenza, con l’unico obiettivo di non deprimere i risultati reddituali di breve andare. A tal riguardo, si …
A hardware skin-segmentation IP for vision based smart ADAS through an FPGA prototyping
2017
International audience; In this paper we presents a platform based design approach for fast HW/SW embedded smart Advanced Driver Assistant System (ADAS) design and prototyping. Then, we share our experience in designing and prototyping a HW/SW vision based smart embedded system as an ADAS that helps to increase the safety of car's drivers. We present a physical prototype of the vision ADAS based on a Zynq FPGA. The system detects the fatigue state of the driver by monitoring the eyes closure and generates a real-time alert. A new HW/SW codesign skin segmentation step to locate the eyes/face is proposed. Our presented new approach migrates the skin segmentation step from processing system (S…
