摘　　要：提出了在TMS320C5416 DSP硬件开发平台上实时实现G.723.1的解决方案。根据G.723.1标准实时实现的要求对程序进行了优化,最终在TMS320C5416 DSP上实时实现了该标准。语音质量良好,达到了通信质量的要求。In this paper, a solution of real-time implementation of G.723.1 on the hardware development platform TMS320C5416 DSP was proposed. Compared with the performance goal for real-time implementation of G.723.1 standard, algorithm brought forward by this standard was improved. Finally the standard was realized on the hardware development platform TMS320C5416 DSP. The voice quality was good enough to meet the requirements of communication quality.
