Samenvatting

Sound-source localization is used in many different
real-time acoustic applications. Microphone arrays have the
potential capability to recognize, profile and locate sound-sources
in noisy environments. The quality response of such sensor
arrays, however, is determined by the quantity of microphones.
A higher number of microphones increases the computational
demand, making real-time response challenging. In this paper,
we present a scalable and runtime reconfigurable architecture to
provide accurate sound-source localization in real-time. On one
hand, the reconfigurable architecture is designed to be scalable in
order to support a variable number of microphones. On the other
hand, we use runtime reconfigurable look-up tables (CFGLUTs)
to provide a dynamic response in real-time. Experiments demonstrate
how an accurate sound-source localization is obtained in
less than a few hundred milliseconds. As far as we are aware,
it is the first time that runtime reconfiguration is applied to a
reconfigurable architecture consisting of a sensor array.
