• Given a machine with 2K of memory and 32 registers, is it possible to build a 20 bit instruction set meeting the following parameters?
  • 25 instructions w/ two register operands (e.g., COPY R1, R2)
  • 5 instructions w/ one register and one memory address (e.g., Load R1, X)
  • 20 instructions w/ one memory address operand (e.g., OUTPUT X)
  • 50 instructions w/ no operand (e.g., HALT)
• If it is possible, show the expanding opcodes that would allow it.
