    Hi,

     

    We are trying to do acoustic processing for TI MSP430F1611 microcontroller. and tried to implement a 512-points FFT within 0.25seconds but not able to squeeze in.

     

    I saw a paper published by Feng Zhao on mPlatform during IPSN2007, and it shows that a 512-pts FFT can be done within 100msec.

     

    Wondering if we can download this code/lib from any of your download site, or is it part of some toolkits?

     

    Thank you very much for your advice.

     

    Regards,

    Shanguo

    Unfortunatly the code is not released at the moment but I can give you some tips:

     

    The compiler is very important (we use IAR). For better performance all constants (like sinwaves)  are pre-calculated and placed in tables in memory.

     

    Hopefully this will help,
