    Utilization of graphics processing unit in sound source localization based on digital beamforming

  • Original language description

    Paper deals with utilization of graphics processing unit (GPU) in sound source localization system which is based on digital beamforming. Due to principle of beamformer operation its localization accuracy increases with increasing number of microphone units in the array but there is a problem how to process this large amount of digital sound data in a short time. Today high-end multi core processors based on x86 architecture used in personal computers are able to run simultaneously up to 12 threads achieving floating point performance near of 100 GFLOPs while graphics processing units can process hundreds of threads simultaneously reaching theoretically up to 2700 GFLOPs in single precision. So the main idea is to move computation intensive tasks to the GPU enabling to free CPU resources to another tasks related to data acquisition, visualization and archiving.
