Hi,
In fixed point speex code there is no where satuartions checks are used. The
basic arithmetic operations like ADD,ADD32,SUB,MUL etc. are just directly
implemented without the saturation checks. Can u please comment on this.
For the speex decoder testing, is there any standard streams? if yes from where
can i get those?
Thaking you all,
Yours,
Jyothiprakash Reddy, T

Can u > please comment on this.The code is written in such a way that no saturating add/sub/mul are required. That's the only way to get any sort of performance on architectures that don't have hardware saturation (e.g. ARM). There's only a few places where saturation is required, which I'm handling with the SATURATE macro.> For the speex decoder testing, is there any standard streams? if yes > from where can i get those?No standard stream, sorry. Speex doesn't have a "bit exact" definition like the ITU codecs. That means I can keep improving it, as long as I maintain bit-stream compatibility (think how much MP3 encoders improved over time).
