| description | In this work the design of an audio codec is presented for VoIP telephony, implemented on a microprocessor MicroBlaze embedded on an FPGA circuit of the Spartan 3E family. The design of the microprocessor is described first, and then, the peripherals to use, among which the handling of an external memory DDR and of a series interface RS232 allowing communicate of the system with a PC computer. In this work, a variant of the algorithm LPC10 is impñemented with speed of 2.4kb/s and the algorithms are implemented in the processor in C language. The evaluation of the system is made from the analysis of the data sent to the PC, which are analyzed with the MATLAB processor and compared with simulated results. This piece of work is related to a task of the project "Platform of Commutation of Packages", approved by the MIC to the ISPJAE with participation of UPR and GKT. |

En este trabajo se presenta el diseño de un codec de audio para telefonía VoIP implementado sobre un microprocesador MicroBlaze empotrado sobre un circuito FPGA de la familia Spartan 3E. Se describe primeramente el diseño del microprocesador y de los periféricos a emplear, entre los cuales se destaca el manejo de una memoria externa DDR y de una interfaz serie RS232 que permite comunicar el sistema con una computadora PC. En el trabajo se implementa una variante del algoritmo LPC10 con velocidad de 2.4kb/s y los algoritmos se implementan en el procesador en lenguaje C. La evaluación del sistema se realiza a partir del análisis de los datos enviados hacia la PC que son analizados con el procesador MATLAB y comparados con resultados simulados. Este trabajo tributa a una tarea del proyecto "Plataforma de conmutaci´ón de paquetes", aprobados por el MIC al ISPJAE con participación de la UPR y GKT.
