The Parallax P8X32A Propeller is a multi-core processor parallel computer architecture microcontroller chip with eight 32-bit reduced instruction set computer (RISC) central processing unit (CPU) cores.[1][2] Introduced in 2006, it is designed and sold by Parallax, Inc.

The Propeller microcontroller, Propeller assembly language, and Spin interpreter were designed by Parallax's cofounder and president, Chip Gracey. The Spin programming language and Propeller Tool integrated development environment (IDE) were designed by Chip Gracey and Parallax's software engineer Jeff Martin.

On August 6, 2014, Parallax Inc. released all of the Propeller 1 P8X32A hardware and tools as open-source hardware and software under the GNU General Public License (GPL) 3.0. This included the Verilog code, top-level hardware description language (HDL) files, Spin interpreter, PropellerIDE and SimpleIDE programming tools and compilers.[3]

In 2020, Propeller 2 (P2X8C4M64P) was released.
