摘要

在数字音频压缩的历史中，已经有许多不同的尝试来降低比特率而不降低相同等级的平等性。今天，我们有许多现代压缩算法，可以在没有明显质量损失的情况下实现非常高的压缩比。我们工作的主要目标是使用ITU-T的G.729推荐实现最先进的语音编码算法CS-ACELP，并对其进行优化，以便在超长指令字(VLIW)数字信号处理器(DSP)中央处理器(CPU)上实时实现。

Real-time implementation and optimization of ITU-T's G.729 speech codec running at 8 kbits/sec using CS-ACELP on TM-1000 VLIW DSP CPU

During the history of digital audio compression there have been many different attempts at reducing the bit rate without reducing the equality in the same grade. Today we have many modem compression algorithms that achieve very high compression rations without a perceivable loss in quality. The main objective of our work is to implement a state of art speech-coding algorithm CS-ACELP using ITU-T's G.729 recommendation and optimize it for real-time implementation on a very long instruction word (VLIW) digital signal processor (DSP) central processing unit (CPU).
