In this paper an example of hardware implementation of binaural sound source localization is presented. Using only two microphones, which correspond approximately to binaural hearing, limits the possibility of exact sound source localization. In contrast to human auditory system (HAS), only the angle of arrival determination is possible in implemented system. Moreover, the angle of arrival (AoA) could be determined here in a limited range of values located on a half-plane. First, the base formulas used by implemented algorithm are shown. Next, selected hardware platforms and peripheral modules are described. The VHDL tools for synthesis and implementation are used. Finally, resources consumed by hardware CPLD/FPGA implementation and selected test results are presented.
