This paper presents a single FPGA implementation of a realtime sound localization system using two microphones. The implementation, utilizing a cross-correlation technique based on a modified version of the phase transform, successfully localizes sound sources in noisy environments with as low an SNR as 10dB. Using the same algorithm and similar hardware architecture, it is shown that up to 5 parallel systems (using 10 microphones), all real-time, can be implemented on a single FPGA while only… CONTINUE READING
