A Novel Systolic Parallel Hardware Architecture for the FPGA Acceleration of Feedforward Neural Networks

2019

New chips for machine learning applications appear, they are tuned for a specific topology, being efficient by using highly parallel designs at the cost of high power or large complex devices. However, the computational demands of deep neural networks require flexible and efficient hardware architectures able to fit different applications, neural network types, number of inputs, outputs, layers, and units in each layer, making the migration from software to hardware easy. This paper describes novel hardware implementing any feedforward neural network (FFNN): multilayer perceptron, autoencoder, and logistic regression. The architecture admits an arbitrary input and output number, units in la…

Parallel macro pipelining on the intel SCC many-core computer

2013

In this paper we present how Intel's Single-Chip-Cloud processor behaves for parallel macro pipeline applications. Subsets of the SCC's available cores can be arranged as a pipeline where each core processes one stage of the overall workload. Each of the independent cores processes a small part of a larger task and feeds the following core with new data after it finishes its work. Our case-study is a parallel rendering system which renders successive images and applies different filters on them. On normal graphics adapters this is usually done in multiple cycles, we do this in a single pipeline pass. We show that we can achieve a significant speedup by using multiple parallel pipelines on t…

Overcoming barriers to evidence-based patient blood management: a restricted review

2020

Abstract Background Blood transfusions are associated with a range of adverse patient outcomes, including coagulopathy, immunomodulation and haemolysis, which increase the risk of morbidity and mortality. Consideration of these risks and potential benefits are necessary when deciding to transfuse. Patient blood management (PBM) guidelines exist to assist in clinical decision-making, but they are underutilised. Exploration of barriers to the implementation and utilisation of the PBM guidelines is required. This study aimed to identify common barriers and implementation strategies used to implement PBM guidelines, with a comparison against current expert opinion. Methods A restricted review a…

Hardware/Software Implementation of Image Processing Systems Based on ARM Processor

2020

International audience; In this paper we present a hardware/software platform for real-time image processing. We start with the creation of the hardware part based on the ARM processor (PS) with various drivers (PL) for reading, recording and displaying images. Using the SDK tool (Software Development Kit), we add software parts for the realization of some basic image processing algorithms. We use the Xilinx-VIVADO2016 tool for the proposed system design and we use the rapid development board (Xilinx-ZedBoard) for practical implementations. To realize the principle of codesign, we add hardware IPs (RTL level) for the implementation of the same image processing algorithms. To avoid the detai…

ERP Post-implementation Issues in Small-and- Medium-Sized Enterprises

2011

This paper focuses on ERP post-implementation issues in Small-and-Medium-Sized Enterprises (SMEs).We conducted a case study in a small Norwegian retail company. We studied the enterprise in the period after going live with their new ERP system. Certain challenges were observed such as security risks because of inaccurate configuration of the system, difficulties with operational issues such as sending invoices and getting sales reports, inaccurate inventory, insufficient training arrangement, workarounds, conflicting incentives among customer, reseller and consultant. There were human consequences for end users since the implementation of the system caused stress among some of the employees…

A feedback view of behavioural distortions from perceived public service gaps at ‘street‐level’ policy implementation: The case of unintended outcome…

2020

This paper discusses the limitations and risks associated with the use of output-oriented measures to assess public school performance. In particular, it questions the capability of the performance measures set by external institutions, with respect to schools, to support sustainable educational outcomes. To this end, the ‘street-level bureaucracy’ theory is used in the paper as a basis to analyse the behavioural distortions generated by perceived public service gaps at school level policy implementation. Such unintended behavioural effects are often a major cause of disappointing outcomes when test-based accountability systems are adopted. In the second part of the paper, an insight model …

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…

Using organizational influence processes to overcome IS implementation barriers: lessons from a longitudinal case study of SPI implementation

2014

A fundamental tenet of the information systems (IS) discipline holds that: (a) a lack of formal power and influence over the organization targeted for change, (b) weak support from top management, and (c) organizational memories of prior failures are barriers to implementation success. Our research, informed by organization influence, compellingly illustrates that such conditions do not necessarily doom a project to failure. In this paper, we present an analysis of how an IS implementation team designed and enacted a coordinated strategy of organizational influence to achieve implementation success despite these barriers. Our empirical analysis also found that technology implementation and …

PGAC: A Parallel Genetic Algorithm for Data Clustering

2005

Cluster analysis is a valuable tool for exploratory pattern analysis, especially when very little a priori knowledge about the data is available. Distributed systems, based on high speed intranet connections, provide new tools in order to design new and faster clustering algorithms. Here, a parallel genetic algorithm for clustering called PGAC is described. The used strategy of parallelization is the island model paradigm where different populations of chromosomes (called demes) evolve locally to each processor and from time to time some individuals are moved from one deme to another. Experiments have been performed for testing the benefits of the parallelisation paradigm in terms of comput…
