| GMM Microscope image of a Nano Pulsar |
NANO Technology is here for the Propeller chip! Take a look at this Nano Pulsar created from Propeller SPIN code that operates inside a single Parallax Propeller chip!
This Nano Pulsar is a mere 10-ns to one side and represents the fastest machine inside the chip, currently known in the Propeller world!
Propeller aficionados may be aware of some techniques provided by Parallax to enable the programming of registers belonging to a configurable state machine. There are 32 different modes that program the most spectacular machines. There are two counter modules per Cog with eight Cogs to a single chip for a total of sixteen powerful state machines. The Brain has taken just one Propeller Counter Module and configured it to a powerful Nanotechnology 10-ns Machine.
