[sdiy] DSP or Micro

I like it all but the price tag and possible dev tools cost, still once I
have a defined target system I might use the ARM on a new board. The ARM
piece price is probably OK given they are selling the whole system at this

Biggest, baddest, overkill DSP? How about this:
* 32-bit ARM Cortex A8 with Neon SIMD running at 1GHz
* Integrated TMS320C64x+ DSP running at 430MHz
* 512 MB DDR DRAM
* on-board stereo codec
* on-board HDMI & S-video
* on-board ethernet, USB, SD, Serial
* GPIO, camera, digital audio, etc expansion connectors
* Runs Linux & other OSes. Do development in a GUI right on the board.
Run Pd, JACK, Chuck, etc.
Or go with the slightly older BB rev C4 for $125 (slower CPU, less
memory, no ethernet)
Note that I'm only partly kidding. While it's possible to do audio work
on these boards, there's a lot of other stuff to learn in the process.
Not for the faint of heart...
