    Hi Stefan,

    its me again with some very good news !! There is an* INTEGER*
    version of the MPC decoder, made for *ARM processors* !! I attach
    it, its VERY small, and L-GPL also, made by a Chinese MPC fan in his
    freetime  ! The sources are only *27 KB*, compiled its less than *17
    KB* !

    BTW, this poll here would maybe interest some of your marketing guys
    :

y145928
    .. it is only several hours old ;-) ...

    Here is my word : If you implement MPC decoding, i organize sales of
    50 units for you guys. I even pay for them from my own pocket, i
    could pay the 7500,- EUR from my bank account if i want to ;-) ....
