Robot Soccer using Optical Analog VLSI Sensors
In this paper we show how a combination of low dimensional vision sensors can be used to aid the higher level visual processing task of colour blob tracking, carried out by a conventional vision system. The processing elements are neuromorphic analog VLSI (aVLSI) vision sensors capable of computing motion and estimating the spatial position of high-contrast moving targets. In these devices both...
متن کاملImplementing Neural Architectures Using Analog VLSI Circuits
Biological systems routinely perform computations, such as speech recognition and the calculation of visual motion, that baffle our most powerful computers. Analog very large-scale integrated (VLSI) technology allows us not only to study and simulate biological systems, but also to emulate them in designing artificial sensory systems. A methodology for building these systems in CMOS VLSI techno...
متن کاملA One-Dimensional Analog VLSI Implementation for Nonlinear Real-Time Signal Preprocessing
R econstruction of given noisy data is an ill-posed problem and a computationally intensive task. Nonlinear regularization techniques are used to find a unique solution under certain constraints. In our contribution we present a parallel mixed-signal architecture which solves this nonlinear problem with in microseconds. By connecting all parallel cells in a circular manner it is possible to pro...
متن کاملAnalog VLSI Hearing Systems
Animals hear through complex mechanical–neural signal processing systems. We would like to be able to duplicate this functionality in machines, for purposes of recognizing speech and for other sound-related tasks. Computational models on digital computers offer one method for exploring models of auditory processing, but in this paper we discuss the use of analog VLSI systems as a promising alte...
