En esta ponencia-demo se presenta una práctica donde se analiza la influencia en el tiempo de ejecución de algunas optimizaciones sobre el código máquina para procesadores reales (familia Intel Pentium). Se propone el estudio del efecto del emparejamiento de instrucciones y de las dependencias entre registros, la aceleración obtenida con el...

Address Event Representation (AER) is an emergent neuromorphic interchip communication protocol that allows for real-time virtual massive connectivity between huge number neurons located on different chips. By exploiting high speed digital communication circuits (with nano-seconds timings), synaptic neural connections can be time multiplexed,...

Address-Event-Representation (AER) is a communications protocol for transferring spikes between bio-inspired chips. Such systems may consist of a hierarchical structure with several chips that transmit spikes among them in real time, while performing some processing. To develop and test AER based systems it is convenient to have a set of...

In this paper we present a mechanism that allows the coprocessing of video in real-time based into Address-Event-Representation (A ER) convolutions chips. Several software methods fur generating synthetic AEK streams from frames stored in a computer's memory are described and evaluated. Evaluation criteria cover execution time, distribution...

Neuromorphic engineering tries to mimic biological information processing. Address-Event Representation (AER) is a neuromorphic communication protocol for spiking neurons between different chips. We present a new way to drive robotic platforms using spiking neurons. We have simulated spiking control models for DC motors, and developed a mobile...

Bio-Inspired and Neuro-Inspired systems or circuits are a relatively novel approaches to solve real problems by mimicking the biology in its efficient solutions. Robotic also tries to mimic the biology and more particularly the human body structure and efficiency of the muscles, bones, articulations, etc. Address-Event-Representation (AER) is a...

En este trabajo, se describe un simulador gráfico denominado Simula Cache 1.0, que facilita la realización de prácticas sobre jerarquía de memoria en cursos de arquitectura y estructura de computadores. Está inspirado en el conocido Dinero III [1], aunque diseñado para un entorno W9x-NT, con una interfaz gráfica muy intuitiva y fácil de...

Neuromorphic engineers study models and implementations of systems that mimic neurons behavior in the brain. Neuro-inspired systems commonly use spikes to represent information. This representation has several advantages: its robustness to noise thanks to repetition, its continuous and analog information representation using digital pulses, its...

Distance calculation is always one of the most important goals in a digital stereoscopic vision system. In an AER system this goal is very important too, but it cannot be calculated as accurately as we would like. This demonstration shows a first approximation in this field, using a disparity algorithm between both retinas. The system can make...

Correcting digital images tilt needs huge quantities of memory, high computational resources, and use to take a considerable amount of time. This demonstration shows how a spikes-based silicon retina dynamic vision sensor (DVS) tilt can corrected in real time using a commercial accelerometer. DVS output is a stream of spikes codified using the...
