GSM AMR Ref. C Code analysis - prakash_sebastian - Sep 9 11:55:00 2002

Hi, Can someone who has implemented the reference C code in DSP assembly give me some inputs on: 1. How much of code similarity is there between the 8 bit rates(maybe in terms of percentage)? 2. Is there any code similarity between the Ref. C Code of GSM AMR and that of G.729AB/G.723.1 ? 3. If anyone has done a function wise division between the 8 bit rates that would be great! Information like which functions are used only for certain bit rates and not for others, would be valuable. Thanks in advance. Prakash. |
