| Abstract: | 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. |
