--- Comment #39 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---

* FETCH FSM will initiate handshake to ISSUE FSM

* ISSUE FSM will initiate handshake to EXECUTE FSM

* EXECUTE FSM will initiate handshake back to ISSUE FSM on completion
  - and also set (optionally) pc_changed, insn_done, and (optionally)

* ISSUE FSM checks loop conditions.  if exiting it will *PASS ON*
  insn_done and pc_changed to FETCH FSM, and initiate
  handshake back to ISSUE FSM

it is important that there be a split there, insn_done is probably


yes it is.
