Y86

Simplified version of x86.

Likely a pun on "why 86?".

5 stage classic pipeline.

No one knows the official spec however: http://stackoverflow.com/questions/13055154/list-of-y86-commands

Verilog implementations:

• https://github.com/Archstacker/Y86-CPU

Assemblers and emulators:

• http://y86.js.org/ https://github.com/quietshu/y86 amazing js pipeline level visual simulation.

  A bit hard to understand however.

  Terminology is that of a digram found copy pasted in several university courses without attribution. Great.
