BONUS: Write the hexadecimal machine code and binary machine code for the following MIPS instruction: or $v0, $a0, $a1. Refer to the MIPS reference card for the opcode format and register addresses. Fill in the binary machine instruction code (as opcode, rs, rt, immediate) below: opcode (6 bits), rs (5 bits), rt (5 bits), rd (5 bits), sa (shamt) (5 bits), funct (6 bits).
