boards as a host. I might use PC-DOS as the OS and my old toolchain
like Turbo Pascal or Turbo C. At GHz speeds, the system would be
blistering fast. It might be possible to port something like FreeRTOS
to get a real time operating system.
But, the x86 chips are microcomputers, not microcontrollers and they
don't have a lot of specialized gadgets such as PWM, I2C, SPI etc.
There is a lot of work going on with the Intel X-Scale chip over at
www.gumstix.com.
The gumstix board has the PXA chip and ram/flash
running Linux and it is coupled to an ATmega128 to handle robot IO.
I have played with this a little bit (the gumstix, not the
combination) and I also have the Blackfin board as a stepping stool to
the Surveyor 'bot. As soon as vision becomes a factor, Linux becomes
important for the code base that's already available.
