The Propeller is a multi-core microcontroller by Parallax.
- 8 cores (cogs)
- 32-bit architecture
- Max clock speed 80MHz (note that Spin code executes much slower than this)
- Each core has 2K SRAM for programs and data
- 32KB EEPROM used to store programs
- Programmable by serial interface
Windows development tools
The Propeller can be programmed in assembler or Spin. There are also third party C compilers available.
The Propeller has a small instruction set and is well documented in the Propeller manual.
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.
- BST (Brad’s Spin Tool) is a cross-platform tool suite for developing Spin programs.
There are two C implementations
- Imagecraft make a commercial compiler, $99 for non-commercial use
- 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
