Hi All I am considering retargeting codec2 / sm1000 etc for another micro . a '21477. and this will include a rather strong modem. (or I might stick with stm32F7)
In opinion, just how much of the STMF4 code for codec2 is hard optimized for the stm? Without spending alot of time looking at it, I am wondering abut the implications for me of using a different processor. IE how much stuff is tightly coupled to the way the stmf4 works ? Part of the deal with getting micros like the M4 to really fly in DSP land (and get them even close to their pure DSP brothers) are tightly writing to the processor and compiler architectures. all opinions welcome. next step will be actually compiling for sharc and seeing what happens. I expect an 'average' result- as the stmf4 is good for multipurpose things, but the SHARC compilers are not. Or rather, the sharc compiler does not in generally utilize the very rich instruction set available to it- only about half of the very fancy instructions of the sharc are used, leading to lacklustre performance for GP computing. glen Vk1XX ------------------------------------------------------------------------------ _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2
