• Given a machine with 1K of memory and 16 registers, is it possible to build a 16-bit instruction set meeting the following parameters?
  • 6 instructions w/ three register operands (e.g., opcode R1, R2, R3)
  • 30 instructions w/ two register operands (e.g., opcode R1, R2)
  • 2 instructions w/ one register and one memory address (e.g., opcode R1, MemAddr)
  • 20 instructions w/ no operand (e.g., opcode)
• If it is possible, show the expanding opcodes that would allow it.
