Parallel implementation of a cellular automaton model for the simulation of laser dynamics
(Springer, 2006)
A parallel implementation for distributed-memory MIMD systems of a 2D discrete model of laser dynamics based on cellular au- tomata is presented. The model has been implemented on a PC cluster using a message passing ...

A Middleware-based Approach for Context-aware Computing
(CEPIS: Council of European Professional Informatics Societies, 2007)
Ubiquitous computing environments integrate a large number of heterogeneous devices, which convey an increasing level of complexity when developing ubiquitous applications. A solution to this problem resorts to the use ...

Compact Calibration Circuit for Large Neuromorphic Arrays
(IEEE Computer Society, 2008)
Low current applications, like neuromorphic circuits, where operating currents can be as low as few nano amps or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precision. Here we ...

Advanced Vision Processing Systems: Spike-Based Simulation and Processing
(Springer, 2009)
In this paper we briefly summarize the fundamental properties of spike events processing applied to artificial vision systems. This sensing and processing technology is capable of very high speed throughput, because it ...

A Two-Level Dynamic Chrono-Scheduling Algorithm
(IEEE Computer Society, 2009)
We propose a dynamic instruction scheduler that does not need any kind of wakeup logic, as all the instructions are “programmed” on issue stage to be executed in pre-calculated cycles. The scheduler is composed of two ...

Fully Digital AER Convolution Chip for Vision Processing
(IEEE Computer Society, 2008)
We present a neuromorphic fully digital convolution microchip for Address Event Representation (AER) spike-based processing systems. This microchip computes 2-D convolutions with a programmable kernel in real time. It ...

A Smart Phone-based Personal Area Network for Remote Monitoring of Biosignals
(Springer, 2007)
This paper presents a system whose purpose is to monitor a patient continuously from indoor or outdoor environments. The system is based on a Bluetooth PAN, carried by the patient, whose central node, a smart phone, ...
