Design goals[editovat]
- Simple to implement in other programming languages
- Efficient to execute by emulator
- Future extensibility (to support 128-bit data/address width or more)
- Single instruction code for any data/address width
- Register based load-store architecture rather than stack based machine or accumulator based machine
