TMS C6711 speech coding - omar nasr - Feb 16 18:26:00 2004

Hello all, I tried for long time to implement the CELP "FS1016" on TMS320C6711, I tried for mmore than 3 weeks but I failed!!!, then I tried to use MELP which use less computations, but till now no way "more than 2 weeks", can u tell me an algorithm that has bit rate about 2.4 kbps and in the same have nice quality and in same time can be implemented in real time!!??? I really need it. what about MBE "multi band excitation"?? is it computationally intensive like the others?? thankx alot for ur time eng.Omar Ahmed Nasr DSP and comm TA- faculty of engineering- Cairo university _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail |

Tends to be a contradiction for today's speech codecs. I think ur best bet is to optimize MELP on C6711. It will certainly run real-time (see my previous post about 65 MIPS full-duplex on C55xx) but you have to spend some time and figure out which functions and algorithm sections are running slow and why. -Jeff |
