G.723.1标准的DSP全汇编实现

DSP Assemble Language Realization of G.723.1 Protocol

TMS3 2 0 C5 4 0 9是 TI的一款高性能的 DSP芯片 ,但在用其实现复杂算法时用全汇编较 C语言效率要高得多。本文主要介绍如何用 TMS3 2 0 C5 4 0 9的全汇编语言来实现 G.72 3 .1语音编码标准。在简要介绍了 G.72 3 .1标准和芯片的选择后 ,文章着重介绍了在编写优化 G.72 3 .1全汇编程序过程中的一些关键问题 ,其中也包含了笔者的一些经验教训。

This article introduces how to realize G.723.1 Protocol on TMS320C5409 by using all assemble language.After brief introducing G.723.1 Protocol and the select of chips,it emphasizes some key problems that found during writing G.723.1 Protocol assemble language.And it also includes most of writer's experiences.
