Research and Analysis on the Implementation of MELP Algorithm on DSP

Abstract:

This paper briefly analyses the principle of MELP vocoder algorithm, and TI's TMS320C5509(C5509) DSP is selected as an implementation platform of 2.4kbps MELP speech-coding algorithm. To ensure the rational and efficient utilization of the limited memory resources, this paper introduces the processing method of MELP algorithm based on frame structure and gives a profound analysis on how to configure its memory space of the selected DSP by analyzing its memory structure and considering the specific circumstances of the MELP vocoder algorithm. Finally, this paper gives the memory configuration during the implementation of MELP vocoder on TI's TMS320C5509 DSP.
