基于USB HOST的语音采集存储系统设计

The Voice Acquisition and Storage System Design Base on USB HOST

以DSP为核心处理芯片建立了具有USB HOST和语音采集的硬件平台,并在平台上进行LINUX系统移植,以及开发和加载语音采集和USB HOST的API函数。该系统最终实现了语音数据采集存储和嵌入式系统对USB存储器进行读写操作,把采集到的语音数据直接保存到USB存储器中,完成了批量数据的存储和传输。实验结果表明,系统具有较强的工业应用价值。

The system took DSP as the core processing chip to establish the hardware platform with USB Host and voice collection, and migrated Linux on the platform, developed and loaded the voice collection and the API function of USB Host. Finally, the system realized the storage of the voice data collection, reading and writing operation of USB memory in the embedded system,. The collected voice data is saved to USB memory directly, and the bulk of data storage and transmission is completed. The experimental results show that the system has strong value for industrial application.
