Determine if it is possible to design an expanding opcode to allow the following to be encoded in a 12-bit instruction. 4 instructions with three registers. 255 instructions with one register. 16 instructions with zero register. If this design is not possible, what will be the maximum size of instruction that would accommodate the design? Show your work and provide explanation.

The instruction is stored at location 300 with its address field at location 301. The address field has a value of 400. A processor register R1 contains the number 200. Evaluate the effective address if the addressing mode of the instruction is Relative Addressing mode; • Relative: 300 + 200 = 500 • Relative: 302 + 200 = 502 • Relative: 301 + 400 = 701 • Relative: 302 + 400 = 702
