Hi! I have some questions about that functions: fir_mem16, iir_mem16 and filter_mem16. Filtering is very slow on TI DSP, and i want to optimise it. Can somebody give me formulas which discribe work of this filters? Or any suggestions about how to transform code for better performance. I going to implement this functions in assembler, but it is hard to do without full understanding how functions

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

Hi evryone ) My name is Vasily. I am a software developer from Ukrane, and i am going to use Speex on TMS320F28335 DSP-controller wich has only 68KB of RAM. And I worry about this. I can't find memory requirements in speex manual(only some about optimization). Can anyone tell me, how many RAM Speex can eat at 8kbs realtime encoding and decoding with echo canceller and jitter buffer enabled?
