Hi all. I work on VoIP solution for Windows Mobile 6 platform. I tried to use echo canceller from libspeex and it works good. However CPU usage is pretty high - UI redraws slowly. Libspeex is compiled with FIXED_POINT define. Also I tried ARM4_ASM define - but it depends on GCC inline assembler. Visual Studio 2008 is not able to compile it. Is there any chance to see ARM assembler source code compatible with Visual Studio inline assembler? What is the ARM CPU usage difference comparing non-assembler build and assember? Thank you :)
