Vocoder VHDL code Request - archies - 10-04-2017 IMPLEMENTATION OF G.726 ITU-T VOCODER ON A SINGLE CHIP USING VHDL The objective of the paper is to design a high density DECODER for handling multi-channels(256) of G.726. ADPCM Decoder in FPGA to convert 64 kbps digital streams in to 40 kpbs, 32 kbps, 24 kbps or 16 kbps using VHDL. high speed advantage because of parallel processing of DSP algorithm. is an advantage of this. The complete multichannel decoder is implemented in ALTERA(EPF10K70RC240-4) FPGA.256 channels can be handled by the parallel logic. In case of serial architecture 50% area saving is achieved, but the number of channels is reduced. G.726 ADPCM VOCODER The Voice coder is one, which Compress & De-compress the voice samples for transmission & reception of voice with limited bandwidth. Waveform coding is used here. there is no latency, very good voice reproduction and less complexity in implementation for waveform coding as compared to other forms of coding like the source coding. ADPCM encoder a difference signal is obtained, by subtracting an estimate of the input signal from the input signal for linear PCM. for more details, refer this pdf: [attachment=3668] Vocoder VHDL code Request - danybabu2004 - 10-04-2017 Plz .. i want VHDL code for The Vocoder .. any 1 can help me in this request ?.. and thx for Attention .. |
