Greetings to All! Now I am trying to run speex on TI DSP... I need only coder+decoder+AEC. Bitrate 8000bps. Building with floating point support. What can i do, to reduce RAM consumption? I mean very serious RAM optimisations. Deleting not used structure fields, etc... May be I can do something with alloc... Help me to determine that it is possible to throw out. What is best result(in RAM

...tack_alloc.h, which tracks the maximum depth of the scratch stack, so that you can tweak the sizes in config.h. You just have to declare the variable and add this init before the call to speex_encoder_init, and go back and look at the variable after you run some data through. #ifdef STACKDBG spxGlobalScratchFree = spxGlobalScratchPtr; #endif If you think that the C5416 build is broken, then (as Jean-Marc said) tell us what version you are using. There is a C54x project in the speex source tree that runs directly in the Code Composer simulator. If that fails in the latest code, let me know and I will wor...
