ITU-T G.711 is a standard to
represent 8 bit compressed pulse code modulation (PCM) samples
for signals of voice frequencies, sampled at the rate of 8000
samples/second. G.711 encoder will create a 64 Kbps bitstream.
This standard has two forms, viz., A-Law and µ-Law. A-Law G.711
PCM encoder converts 13 bit linear PCM samples into 8 bit
compressed PCM (logarithmic form) samples, and the decoder
does the conversion vice versa. µ-Law G.711 PCM encoder
converts 14 bit linear PCM samples into 8 bit compressed PCM
samples.
In addition to G.711 (A-Law and µ-Law)
companding, the implementation also supports G.711 Appendix 1
and Appendix 2 which defines Packet Loss Concealment and silence
suppression.
Currently Encore’s G.711 is available on TI’s
TMS320C64x (c64x), TMS320C62x (c62x), TMS320C54x (c54x),
TMS320C55x (c55x), Coldfire (MCF52xx, MCF53xx, MCF522xx),
PowerPC, ARM platforms.
