All this processing power is not really needed for my EDM app or if
using the G-100, what I liked was ready to use modules for user
interface, if I use a PIC or a DSP I'm on my own when it comes to
producing a video stream out, even at 150Mhz I'm assuming it would be
tricky to write a program that could do that and other tasks at the
same time. It looks like that for minimal outlay I could develope an
app that could handle a VGA tft display a mouse and a key board and
still have processors left over for comms to a PC and pulse generation
for the EDM.

demoboard $129
software $free

I'm certainly not trying to suggest it is the be all and end all but
you could for example use one of these chips in tandum with a higher
performance DSP, use this to give the other commands and let this one
deal with display issues.
