Communication Contract

• Defined Interfaces

  1. Daisy-Chain to Daisy-Chain (incl' CPU)
  2. Global Bus to CPU
  3. CPU Daisy-Chain code CPU global bus code
     • Start Command takes 2 unsigned ints x then y.
     • Returns a unsigned int == 1 if there was a block there.
  4. CPU Global Bus Code to Lexer
     • Lexer asks Global bus for function at arbitrary location
       • Lexer responds with either a function or NULL (no block at location) == enum`
       • Currently the CPUs unsigned int implementation.
     • Start Command to propagate, returns the same as point #3's return val
  5. On-Block Daisy-Chain to Global Bus
     • Daisy Chain calls a global bus function that sets comm address.
       • Function returns failure so the daisy knows not to propagate.
     • Timing and orchestration will be decided on separate contract.
  6. Parser to CPU Global Bus Code (For error lights).
  7. Interpreter to CPU Global Bus Code (For program outputs).
