<title>Achieving high performances at lower cost for real-time image rotation by using dynamic reconfiguration</title>
2001
FPGA components are widely used today to perform various algorithms (digital filtering) in real time. The emergence of Dynamically Reconfigurable (DR) FPGAs made it possible to reduce the number of necessary resources to carry out an image processing application (tasks chain). We present in this article an image processing application (image rotation) that exploits the FPGA's dynamic reconfiguration feature. A comparison is undertaken between the dynamic and static reconfiguration by using two criteria, cost and performance criteria. For the sake of testing the validity of our approach in terms of Algorithm and Architecture Adequacy , we realized an AT40K40 based board ARDOISE.
An Efficient Hardware implementation of MQ Decoder of JPEG2000
2014
International audience; JPEG2000 is an international standard for still images intended to overcome the shortcomings of the existing JPEG standard. Compared to JPEG image compression techniques, JPEG2000 standard has not only better not only has better compression ratios, but it also offers some exciting features. As it's hard to meet the real-time requirement of image compression systems by software, it is necessary to implement compression system by hardware. The MQ decoder of the JPEG2000 standard is an important bottleneck for real-time applications. In order to meet the real-time requirement we propose in this paper a novel architecture for a MQ decoder with high throughput which is co…
Modeling wave propagation in elastic solids via high-order accurate implicit-mesh discontinuous Galerkin methods
2022
A high-order accurate implicit-mesh discontinuous Galerkin framework for wave propagation in single-phase and bi-phase solids is presented. The framework belongs to the embedded-boundary techniques and its novelty regards the spatial discretization, which enables boundary and interface conditions to be enforced with high-order accuracy on curved embedded geometries. High-order accuracy is achieved via high-order quadrature rules for implicitly-defined domains and boundaries, whilst a cell-merging strategy addresses the presence of small cut cells. The framework is used to discretize the governing equations of elastodynamics, written using a first-order hyperbolic momentum-strain formulation…
How store design contributes to the evolution of retail brand positioning : a longitudinal case study
2014
One of the innovative ways favoured by retailers to drive change in their value proposition is to review the design of their stores. Academic contributions to the in-store experience have mostly focused on consumer perspective and identifying relevant managerial practices. The core of this research studies how repositioning a retail brand translates into the experiential design of retail spaces. To this end, the research follows the repositioning process from a managerial perspective and updates the mechanisms that underlie it. The longitudinal study of embedded cases reveals the importance of an holistic design that takes into account the desired interactions between the shopper and the st…
Moving enterprise resource planning (ERP) systems to the cloud: the challenge of infrastructural embeddedness
2021
Cloud enterprise resource planning (ERP) solutions allow organizations to support and coordinate key business processes by leveraging virtualization. Nevertheless, moving ERPs to the cloud is not straightforward, and organizational cloud ERP initiatives raise multiple concerns. We conducted an in-depth systematic review of relevant research literature and identified six key concerns related to cloud ERP implementation: a) the introduction of new ERP work arrangements, b) the migration of legacy data, c) the assurance of compliance with extant rules and regulations for security, d) the continuous alignment between ERP functionality and business processes, e) the ongoing integration between E…

Evaluation of an Alternative for Increasing Switch Radix
2011
In large switch-based interconnection networks, increasing the switch radix results in a decrease in the total number of network components. In this paper we evaluate an interesting strategy for building high-radix switches going beyond the integration scale bounds. This approach is independent of the evolution of single-chip switches and will remain valid as integration scale keeps evolving. Simulation results show that with a correct internal switch design, this kind of switches achieves almost the same performance as single-chip switches with the same radix, which would be unfeasible with current integration scale.
SimuRed: A flit-level event-driven simulator for multicomputer network performance evaluation
2009
The interconnection network is one of the most important multicomputer components, since it has a great impact on global system performance. Many models and simulators have been proposed to evaluate network performance. This paper presents SimuRed, an event-driven flit-level, cycle-accurate simulator to evaluate different orthogonal network configurations. The core of the simulator has been designed to be expandable and portable to different situations. Some of the advantages of this simulator over other similar tools are its visual interface, its fast execution and its simplicity. Moreover, it is multiplatform and its source code versions (C++ and Java) are freely available under GNU open-…
CRACK PROPAGATION IN FINITE ELEMENTS AUGMENTED WITH EMBEDDED INTERPHASES
2022
In the FE analysis of quasi-brittle materials, one of the main issues is how to correctly capture cracks propagation. In particular, under specific load intensity, strains progressively localize in narrow bands, leading to a global nonlinear softening response until collapse. A variety of FE models have been proposed, which may be separated in two main groups: discrete crack models and continuous models. Discrete crack models introduce a discontinuity along the inter-element boundaries or inside elements (intra-element discontinuity). Continuous models modify the constitutive relations of the local material to better describe its behaviour in presence of a fracture. In the framework of intr…
The role of embeddedness and top management teams on subsidiary initiative
2018
The importance of subsidiaries reaches its pick with their entrepreneurial role. Subsidiary initiatives (SI) are seen as “discrete, proactive undertaking that advances a new way for the corporation to use or expand its resources” (Birkinshaw, 2014, p. 203), which starts with the identification of an opportunity and should achieve the commitment of resources. Nonetheless, though initiatives are beneficial for the entire MNC (Bartlett & Ghoshal, 1988; Birkinshaw & Hood, 2000; Birkinshaw et al., 2005), they are not necessarily well receive by HQ but instead the MNC corporate immune system activates and initiative are rejected (Birkinshaw & Ridderstråle, 1999). This happens because initiatives …
