Speex dev - Nov 2008 - Speex DSP porting

Hello Developers,
 
I am considering using SPEEX on an embedded processor that is in fact a
DSP with fixed point
24 bit resolution. This DSP is named 'Kalimba' and is present in
CSR's
product:
BLUECORE5.
 
I'm very interested if anybody can tell me if porting is possible (in
fact if there are sufficient resources) for implementing a real-time
encoding-decoding (duplex). I'm interested in 4kbps bitrate. 
 
Any help will be greatly appreciated.
 
Thanks,
 
Horia

Speex requires at *least* a 16x16 multiplier and a 32-bit adder, so your
chip meets the requirement for that (you just won't benefit from the
24-bit multiplier unless you do a separate port to that). The only
question is whether it's fast enough and there's no way I can answer
that with the spec you just gave.

Cheers,
