摘要
介绍了 CVSD(连续可变斜率增量调制 )的基本原理和基于 DSP系统开发语音编码的过程。具体讨论了 TMS32 0 C5 4 x 定点 DSP芯片 ,结合 CCS开发平台的特点探讨了TMS32 0 C5 4 x系列在实现
The article introduces fundamental principle of the Continuously Variable Slope Delta modulator and describes the process of Speech Encoding based on DSP system. Specially,we discuss the feature of TMS320C54x, a kind of fitted point digital signal processor.Associating the Code Composer Studio IDE, we also probe into some effective methods in ADM Speech Encoding based on DSP system.
