SAP-1 Implementation from the book Digital Computer Electronics by Albert Malvino and from Brian Eater's 8-Bit Computer Video Series
- testbenches in
test/are mostly for visual checks at the moment. Not actually asserting pass/fails. - instruction RAM is magic ram at the moment, contents immediately available when address changes.
- OPCODEs mirror Brian Eater's implementation and may not necessarily match the book.
- Change all active lows to active highs, for consistency
- create a more reasonable
controller.v - implement halt opcode
