No its refers to the 68000 series processors. Most DSP chips are not
capable of running something like linux nativly, you run linux on a host
processor that controls the DSP.

Porting the opcodes of pure data to a 56k DSP would be an enormous
ammount of work, and you'd probably get similar price/performance by just
buying a faster CPU anyway.

If we had audio over firewire working you could offhand the DSP work to a
stack of cheap miniitx boxes or something, but we dont ;)
