摘　　要：提出了一种基于TMS320VC549定点DSP微处理器芯片的语音信号压缩/解压缩处理系统。该系统采用TLC320AD50C模数、数模转换器,采样率为8 kHz,处理能力为100 M IPS。系统配置有大容量存储器,具备资源扩展能力,适用于语音信号压缩/解压缩和语音识别、语音合成等其他领域。实验结果表明,系统对语音信号的压缩解压缩处理具有稳定性、灵活性和通用性。A speech compression and decompression processing system based on TMS320VC549 16 bit fixed - point DSP chip is proposed in this paper, which is designed by using TLC320ADSOC A/D converter and D/A converter, and with 100MIPS processing capacity and 8kHz sample rate. The system is applicable for speech coding , recognition, synthesizing and so on. The experimental results show that the system is stable, flexible and universal for speech compression and decompression processing.
