Open Source (BSD license) CPU. The RISC-V CPU going to production is a game changer for the Open Source Hardware community. Note that the hardware used is not open source. The part that is open source is the Instruction Set Architecture. The next revolution towards true open source comes when the actual semiconductor fabrication will become open source, which currently does not exist, and is one of the last frontiers for OSE and the open hardware non-movement.

Layers of Abstraction to be Open Sourced

  • Software applications to hardware - [1]
  • Layers of abstraction - noting the position of Instruction Set Architecture - [2]. There is software and hardware. Instruction Set architecture is not hardware - it determines the hardware - or is implemented in hardware - but the dividing line for hardware should perhaps begin with Microarchitecture - which are the actual circuit paths on chips.
