摘要
本文介绍了新一代定点DSP芯片——TMS320C54x的体系结构和特点,及应用单片C548实现高质量、低延时的G.729协议的语音编码算法,并分析了定点DSP在实时实现数字语音通信中的一些关键技术。
The architecture and charac- teristics of TMS320C54x that is the new generation of fixed point DSP chips are introduced in this paper.It is shown that the speech coding algorithm G.729 charac- terized by high quality and low delay can be realized by using a single chip C548.Some key tech- nologies which should be con- cerned in using the fixed point DSP to realize relevant speech coding algorithms in real time are also analyzed.
