Optimization implementation of the linear predictive coding analysis for speech signal on DSP
Kun Gu, Geng Zhao · 2006
The Linear Predictive Coding(PLC) analysis of speech signal is an important part in speech(coding,) it takes the most time in speech coder calculating,in order to improve the speed of speech coding,LPC analysis was implemented in assembly language based on the C54x DSP and optimized in this paper.Compared with the original method,the run time of the coder can be reduced to 5%.
