-====== Propeller Microcontroller ======
-The Propeller is a microcontroller by Parallax.
-===== Specs =====
-cores (cogs)
--bit architecture
-Max clock speed 80MHz (note that Spin code executes much slower than this)
-Each core has 2K SRAM for programs and data
-KB EEPROM used to store programs
-Programmable by serial interface
-VGA output
-Windows development tools

-  * [[http://propeller.wikispaces.com|Wikispaces Propeller Wiki, lots of useful info]]
-  * [[http://en.wikipedia.org/wiki/Parallax_Propeller|Wikipedia entry, good detail]]
-===== Languages =====
-==== Assembler ====
-The Propeller has a small instruction set and is well documented in the Propeller manual.
-==== Spin ====
-A bytecode interpreted language by Parallax.  Most of the high level libraries are written in Spin.  Each cog can fit a copy of the interpreter in its SRAM, but bytecode is read from hub memory which slows down execution.  See the wikipedia page for details.
-==== C ====
-There are two C implementations:
-  * [[http://www.imagecraft.com|Imagecraft]] make a commercial compiler, $99 for non-commercial use
-  * [[http://forums.parallax.com/forums/default.aspx?f=25&m=339139|Catalina]] is an open source compiler currently in beta.  It is based on the lcc compiler and comes with a complete ieee floating point implementation
-==== Other open/free development tools ====
