Yes, have a look at the _bfin.h, _sse.h and _arm.h files to get an idea of what's useful. Also, note that most calls to *_mem2() functions have been (and are being) converted to the _mem16() version. > You should make sure that you run the latest code from Subversion, which has > some speed improvements from 1.1.12. Yes. I'm making big improvements for embedded systems, the last one being 5 minutes ago. Jea...

Hello, I'm trying to use speex for implementing a VoIP demo application using linphone on an embedded system. At the moment I'm not really able to do real time encoding, and thinking about making an assembler port for speex to the AVR32 architecture. The AVR32 is a new hybrid MCU/DSP fixed point processor running at 120Mhz in my application. Does anyone have experiences/info about the

Hi, I can see that there has been some effort to compile the SPEEX codec to operate on the TI c54x and c55x DSPs and I am wondering if anyone would be able to update the mailing list with their current MIPs and Memory resource requirements for their c54x and/or c55x compilation? The only estimate I was able to find in the mailing list archive was 42MIPs but I'm not sure if this is an

...s at least one CPU-intensive place (inner_prod) where I have to use many shifts in a loop to prevent overflows, but those could be replaced by a single shift at the end when using a 40-bit accumulator (which can also replace the only use I have of spx_word64_t). The second thing is in the filters (*_mem2() functions). The reference implementation assumes that writes are as fast as reads. This is often not true on DSPs (at least on Blackfin), so it is possible to re-write the algorithm to take that into account. There is an example (in C) for filter_mem2() and compute_impulse_response() at the end o...
