Abstract

BRAVO GARZON, Víctor Alfonso; NAVARRO BARENO, Jesús Jair  and  G, Edwar Jacinto. Design and implementation of a digital audio codec with FPGA, PCM format, 2 channel with user interface. Tecnura [online]. 2010, vol.14, n.26, pp.56-68. ISSN 0123-921X.

This document describes the process to create a device of digital process with encoding process and decoding in PCM format, with the development of digital filters and the picoblaze microprocessor by means of the implementation in Spartan-3E Starter KitBoard from XILINX, also it describes the work out made about some modules that have this one in order to get the best quality in device, other phases with less value as the signal conditioning, amplification in phase input and output, as well as joining together toward the board.

Keywords : Digital filter; PCM; Picoblaze; Processing; VHDL.
