摘要
Abstract
Based on sound source localization algorithm model, a real-time sound source localization system using digital signal processor ( DSP ) was established. Combining with digital MEMS acoustic sensor, a spatial cone six-element microphone array was used to build localization array. DSP was used as system platform of algorithm imple-mentation,completing the data acquisition module and data processing module design. IIS audio data transmission was analyzed,including the establishment of data transmission channel and the DMA way to work. Test results verified that the performance of the system core modules achieved the expected results,and had a good usability.关键词
