Resource-efficient hardware implementation of a neural-based node for automatic fingerprint classification

2017

Modern mobile communication networks and Internet of Things are paving the way to ubiquitous and mobile computing. On the other hand, several new computing paradigms, such as edge computing, demand for high computational capabilities on specific network nodes. Ubiquitous environments require a large number of distributed user identification nodes enabling a secure platform for resources, services and information management. Biometric systems represent a useful option to the typical identification systems. An accurate automatic fingerprint classification module provides a valuable indexing scheme that allows for effective matching in large fingerprint databases. In this work, an efficient em…

Improvement of Fingerprint Sensor Reading Using FPGA Devices

2008

In order to realize fingerprint recognition system in real time environment, we describe in this paper signal controller to read fingerprint sensor generated in FPGA devices. Basically this signal is generated using state machine. The simulation result for behavioral simulation and signal generation read by logic analyzer are presented in this paper. Initialization and reading time for 76800 pixels are 50.99 mS. It is faster than fingerprint sensor using USB connection, which is more than 250 ms.

FPGA-based embedded Logic Controllers

2014

In general case, reconfigurable logic controllers (RLC) are included into reactive digital embedded systems, carrying out control for several processes proceeding concurrently. The paper presents a practical application of a formal, rule-based specification language in Gentzen sequent logic, which is used as an intermediate textual description of a control interpreted Petri net. On the other hand exactly the same description serves also as logic design expressions, related with different versions of functionally equivalent concurrent state machine models, considered on Register Transfer Level. The symbolic rule-based specification of Petri net-based embedded Logic Controllers (LCs) can be s…

Hardware implementation of content based video indexing algorithms

2005

This paper focus on hardware implementation of content based video indexing techniques by using the FPGA technology. We aim to propose hardware modules that can satisfy requirements of constrained applications, such as real time applications and complex applications that can combine a large number of techniques in the same indexing system. We represent tow examples of micro-architectures related to the dominant colors descriptor and the compact color descriptor.

Accelerating bioinformatics applications via emerging parallel computing systems [Guest editorial]

2015

The papers in this issue focus on advanced parallel computing systems for bioinformatics applications. This papers provide a forum to publish recent advances in the improvement of handling bioinformatics problems on emerging parallel computing systems. These systems can be characterized by exploiting different types of parallelism, including fine-grained versus coarse-grained and thread-level parallelism versus datalevel parallelism versus request-level parallelism. Hence, parallel computing systems based on multi- and many-core CPUs, many-core GPUs, vector processors, or FPGAs offer the promise to massively accelerate many bioinformatics algorithms and applications, ranging from computeint…

Gestione dell’irrigazione del vigneto attraverso l’uso di modelli di simulazione e misure di campo.

2008

In the paper the applicability of a numerical model, i.e. SWAP (Soil Water Atmosphere Plant), and a functional model, i.e. FAO 56, for irrigation scheduling is assessed. Model validation was initially carried out through the comparison between simulated and measured water content of a soil profile. The two models were then used in order to verify the possibility to simulate the typical irrigation management of the study area. In particular, the attitude of the two models to simulate the number and the distribution of watering, as well as the seasonal water consumption found in the ordinary management irrigation was assessed. Different scenarios of irrigation management allowed the analysis …

Hardware implementation of real-time Extreme Learning Machine in FPGA: Analysis of precision, resource occupation and performance

2016

Extreme Learning Machine (ELM) on-chip learning is implemented on FPGA.Three hardware architectures are evaluated.Parametrical analysis of accuracy, resource occupation and performance is carried out. Display Omitted Extreme Learning Machine (ELM) proposes a non-iterative training method for Single Layer Feedforward Neural Networks that provides an effective solution for classification and prediction problems. Its hardware implementation is an important step towards fast, accurate and reconfigurable embedded systems based on neural networks, allowing to extend the range of applications where neural networks can be used, especially where frequent and fast training, or even real-time training…
