&gt; Check out Parallax&#39;s Propeller. May be too expensive depending on what you&#39;re doing, but it meets the specs (except DMA):<br>

&gt; I used one in my Laser Range Finder<br>
&gt; (<a href="http://www.grandideastudio.com/portfolio/laser-range-finder/" target="_blank">http://www.grandideastudio.com/portfolio/laser-range-finder/</a>)  It was<br>
&gt; a bit of a learning curve, but ultimately very powerful and cool.<br>

Not too much there about the GPIOs, but I found the discussion of system<br>
