HVXC解码算法的定点化及优化

Fix-point Processing and Optimization of HVXC Decoding Algorithm

讨论了HVXC解码算法的定点化。考虑到嵌入处理器的运算速度一般较低,为进一步降低HVXC解码算法的复杂度,还介绍了VXC解码算法所采用的优化处理方法。经过定点化处理和优化处理的HVXC解码算法已成功应用于一个实用的嵌入式语音合成系统中。

The paper presents fix-point processing of HVXC decoding algorithm. In order to reduce the complexity of HVXC decoding algorithm to suit the processing ability of the embedded processor, the optimization methods to HVXC decoding algorithm are presented. Recently, the HVXC decoding algorithm processed by fix-point processing and optimization methods has been implemented in an embedded TTS system successfully.
