Exercise 1 Let us consider translating the following MIPS assembly code into a machine code. Note that the instruction format consists of 6-bit opcode, 5-bit rs, 5-bit rt, 5-bit rd, 5-bit shamt, and 6-bit function code. The opcode and function code for "add" are 000000 and 100000. Answer in binary format as well as in hexadecimal format. add $2, 83, 84 18 Exercise 2 It is desired to load A[3] into $8 (i.e., $8
