What high-level languages call goto is usually called a jump instruction in assembly language. The catch is that you can't have a 6-bit opcode and a 32-bit (immediate) memory address fit in one 32-bit instruction. MIPS handles this a little strangely, so let's make a more normal jump instruction called jump, which takes two words. The first is the instruction with the opcode, the second is just the 32-bit jump target address. Thus, jump 0x12345678 would be encoded as two words: 0x10000000 and 0x12345678. Executing that instruction would make the next instruction be taken from memory address 0x12345678. Add states to the following to implement the jump instruction.
