But, the whole Propeller idea is really stupid, aimed at people who can't comprehend a task scheduler, real time OS, or multiprogramming. So, you put each task on a separate virtual CPU and let it multiplex the hardware among the tasks. This is just like Intel's hyperthreading X 8, instead of just X 2. That is great for an OS that does a horrible job of multitasking (read Windows), but really not useful at all on an OS that does it well (read Linux). <rant off> Even though the Propeller's CPU instances each run at 80 MHz, the overall performance is WAY down, because it is doing 8-bit operations on 8-bit memory at that speed. I thought the Z-80 was the bee's knees in 1976, but it is now obsolete by about 30 years!
