Abstract :
The paper describes a comparison of a C implementation of a linear predictive voice coder (LPC) and an implementation based on Spectron Microsystem´s Signal Processing Operating System (SPOX). The hardware platform was a Texas Instruments TMS320C30 Evaluation Module. The SPOX and C implementations were compared based on execution time, ease of program development and maintenance, and portability to different hardware platforms. The vocoder algorithms and the results of the comparison of both implementations are presented
