摘要
本文介绍了CVSD语音编译码原理,对CVSD编码仿真建模,仿真分析了量阶参数对编码性能的影响。在TMS320C6455芯片进行了软件实现,并利用CCS的Profile进行了代码优化分析。
CVSD coding principle is introduced first, encode and decode simulation model of cvsd is constructed, performance impact of delta paramter is analysed with the simulation model, cvsd coding is implemented based on TMS320C6455 chip, then coding optimized with Profile tool provided by CCS ide.
