Abstract :
Efficiently implementing complex voice enhancement algorithms on digital signal processor platforms is a challenging task. A wide scope of knowledge and skills to understand algorithm details, DSP architecture and instruction set, fractional number arithmetic, performance measurement and optimization are essential. In this paper, implementation aspects of the typical voice enhancement related algorithms on Freescale StarCore SC3400 based DSP platform are presented.
