Yes, that's what inspired me to look into the Propeller, which is an interesting architecture with 8 cores and no interrupts; instead of interrupts, you just dedicate one or more cores to polling for input, while the other cores continue on doing their thing with no interruption.

The GA144 basically looks like an even more extreme version of that idea. Instead of eight small cores, it has 144 really small cores. So now I'm trying to figure out which I want to start playing around with; a Propeller, a GA144, an FPGA, or something else.
