This paper presents a novel macro-pipelined sound source localization system . The system employs a small 4-microphone array and uses the time-delay estimation method. By exploiting the parallelism of the cross-correlation algorithm, and using a macro-pipelined structure, the proposed system achieves both high accuracy and quick response capability. To verify the solid performance of the proposed sound source localization system, we present the various experimental results for the sound sources at all directions within 1.5m distance, which shows that the error of azimuth is limited in ±10°.
