Simulador de sistemas AER basados en eventos

Abstract

Address-Event-Representation (AER) is a communications protocol for transferring (visual) information between chips, originally developed for bio-inspired vision and audition systems. Such systems may consist of a complicated multi-layer hierarchical structure with many chips that transmit events among them in real time, while performing some complex processing (for example, convolutions, competitions, etc). This sensing and processing technology is capable of very high speed throughput, because it does not rely on sensing and processing sequences of frames, and because it allows for complex hierarchically structured cortical-like layers for sophisticated processing. In this paper we present an effective tool that simulates the behaviour of such kind of structures. AER stream sources are fed to the software simulation tool and AER streams at all nodes of the network are computed. The tool has been developed in MATLAB and is event driven. It has been conceived as an open tool, so that any user can add extra functional blocks easily, or provide more elaborate or more simplified descriptions of already available blocks.
