[Speex-dev] fir_mem16,iir_mem16 and filter_mem16 optimisations

[Василий Троцкий]

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 work.
