Design goals

  • 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
