| 摘 要： | 为了满足语音信号处理算法实时实现研究的需要,提出了一种以TMS320VC5402为核心的语音处理平台的设计方案。该平台包括JTAG接口电路、闪速(FLASH)存储器的扩展电路、语音采集和语音输出电路,并提供相应电路的硬件实现。目前该平台可以很方便地实现数字滤波、语音增强、语音识别等语音信号处理算法,为研究语音信号算法的实时处理奠定了基础。

| Abstract: | A real-time speech processing platform which based on TMS320VC5402 is proposed. The platform includes JTAG IO circuit,Flash memory expanding circuit,speech signal sampling and output circuit. The hardware implementation is also provided. Based on that, speech algorithms such as digital filter,speech enhancement and speech recognition can be realized conveniently. This platform facilitates the further study of future speech signal real-time processing. |
