  • MEMS microphone array with incorporated beamforming on FPGA platform [Elektronski vir]
    Salom, Iva ...
    A design of an electroacoustic prototype for localization of a dominant noise source in the living and working environment is presented in this paper. Presented prototype is based on the conventional ... delay-and-sum beamforming algorithm which is implemented on a Field Programmable Gate Array platform, (FPGA). Sound signals are provided by receiver system, based on a digital MEMS microphone array. The circular array is oriented in a horizontal plane, enabling 360 degrees of acoustic viewing angle. Configuration enables the implementation of the beamforming algorithm in real time. Additionally, FPGAs brings many benefits in terms of safety, reliability, rapidity, and power consumption. The system has been designed using rapid prototyping methodology with Matlab Simulink tools. Prototype was build, tested and used to validate numerical simulations. A performance evaluation of the FPGA design is presented in terms of hardware resources for the chosen Xilinx Spartan-6 family.
