Propeller Information
New Parallax Design Required Years of R&D
What can you do with eight 32-bit processors (COGs) in one chip? Real simultaneous multi-processing! The new Propeller chip is the result of our internal design team working for eight years.
The Propeller chip was designed at the transistor level by schematic using our own Altera Stratix tools to prototype the product. The Propeller chip is programmed in both a high-level language, called Spin™, and low-level (assembly) language. With the set of pre-built Parallax “objects” for video, mice, keyboards, RF, LCDs, stepper motors and sensors your Propeller application is a matter of high-level integration. The Propeller product line is recommended for those with previous microcontroller experience.
Propeller chips represent the first custom all-silicon product designed by Parallax.
