Hi, I am evaluating the opus codec for use in an embedded design. I have successfully ported opus on a TI C5502 (fixed poin dspt) but need to use a more powerful dsp processor for our application. With the C5502 it takes 4.5ms to encode 2 (mono) channels with a 5ms frame @80kbits per channel. I need to reduce the computing time to reduce latency and leave some time for the DSP to perform some other tasks.The...

Jim, Thank you very much for your suggestions. I managed to get the C55x code working on the simulator. I would like to port Speex both on a C5502 EVM and a C5509A EVM. As such, if you can provide me with the details of your port on the C5509A, it would be greatly appreciated. Furthermore, I am looking for some technical documentation on the CELP algorithms. I would like to better understand the math being implemented. Do you know where...

Hi, My name is Jean Quirion and I am a DSP engineer. Currently I am working on a project where it is desired to implement a VoIP solution over a GSM GPRS link. I would like to use Speex as the vocoder for this application. This application would require the Speex encoder/decoder and possibly the pre-processor to run on a low power fixed-point DSP such as a TI C55x. Thus, I am interested in
