Abstract: An efficient and minimum hardware implementation for the Voice data compression and decompression will be presented in this paper. Voice data compression and decompression is about a process which reduces the data rate or file size of digital audio signals. This process reduces the dynamic range (with out changing the amount of digital data) of audio signals . The Huffman coding is used to have lossless audio compression. Very High Speed Integrated Circuit Hardware Description Language (VHDL) is used for to code the Huffman encoder and decoder and Actel’s Pro ASIC kit is used for hard ware implementation of it. This system is minimal model of real time audio compression and decompression system.
Keywords: FPGA, VLSI, ADC, Huffman Coding.
