Parallax Propeller 1 P8X32A Released as Open Source Design

Exciting!  Parallax posted on their website:

Propeller 1 Open Source | Parallax Inc

"the Propeller 1 (P8X32A) is now a 100% open multicore microcontroller, including all of the hardware and tools: Verilog code, Spin interpreter, PropellerIDE and SimpleIDE programming tools, and compilers. The Propeller 1 may be the most open chip in its class."

 

You can run it on an FPGA:

"The Propeller 1 file set consists of the Verilog files and top-level HDL that lets you run the design on two FPGA board options:

 

  • Terasic Cyclone IV DE0-Nano Evaluation Board - To fit within the low-cost DE0-Nano, we prepared a version without the bitmap character generator for the Parallax custom font (from $8000 to $BFFF).
  • Altera DE2-115 FPGA Development Board - This full version includes the bitmap character generator for the Parallax custom font."

 

cheers,

    [Discuss] Open source Propeller microcontroller

    The only other in-production open-source microcontroller we are aware of is the Sun/Oracle SPARC series, but despite some high-level architecture similarities, the two are in completely different classes. If anyone knows of any other production open-source microcontrollers, please let me know. We released the Verilog code under the GPL v3, so any derivative works, based off of the code we are releasing, will also be open source. I had spoken earlier at the open-hardware summit about open-source hardware being a spectrum; we are going full open. Now you can buy an open-source hardware product and not only download the design files for the circuit board, but also for the microcontroller it supports.
