Dspic for FTT

Hello,
Am working on project, and I have to do FFT of an signal coming from sensor.
please I have this questions:
1/ Which Dspic do I chose for doing this at 8Mhz
2/Which library do I need to do it? can I use Matlab ? 
 3/other thing that you want to suggest.?
 
Thank You

    4.5 (2)
    Each of the 2 accelerometer x 3 (xyz) channels will have an output:
    -signal: energy measurement over a bandwidth of at least 7kHz. Ideally 10kHz. It will contain 2 to 3 orders of the fundamental.
    - The harmonic 1 (expressed in dB)
    -we expect a sampling frequency of the order of 20kHz to 30kHz
     
     
    so it's for me to chose the dspic (or pic32 ??) to get real time FFT of this 6 signal, I can use 2 dspic .
    and get the first harmonic. 
     
    thank you
