摘要
在分析PC机ISA总线结构和PnP协议规范的基础上,结合DSP芯片自身的特点,通过扩展DSP的中断和DMA功能,实现了DSP对网卡和声卡的直接操作,从而设计了一套基于DSP的高性能语音录放、存储及传输系统。
On the basis of analyzing the ISA bus structure and the PnP protocal,a high performance system of voice record-played,storaged and transmitted based on DSP is designed.It is realized by extending the interrupt and DMA function of DSP and the DSP's direct opera-tion on network card and audio card.[
