For 1 Rx channel + 1 Tx channel, G.729 typically takes 10 to 20MIPs on a 
DSP, depending how you count MIPs, and what the DSP chip is. It 
typically takes 80 to 100MIPs on a Pentium, depending on the 
implementation. The IPP stuff doesn't make a huge difference, as it 
doesn't seem to speed things up a great deal. On a 3GHz Pentium you can 
typically run about an E1's worth of G.729 channels. A really efficient 
version might get you to 2 E1s, but I haven't seem one that quite gets 
that far.
