Q4. For each MIPS instruction, show the value of the opcode (OP), source register (RS), and target register (RT) fields. For the I-type instructions, show the value of the immediate field, and for the R-type instructions, show the value of the destination register (RD) field. addi $t0, $s6, 4 add $t1, $s6, $0 sw $t1, 0($t0) lw $t0, 0($t0) add $so, $t1, $to Q5. Assume that registers $50 and $sl hold the values 0x80000000 and OxD0000000, respectively. Answer the following: a. What is the value of $t0 for the following assembly code? add $t0, $so, $s1 b. Is the result in $t0 the desired result, or has there been overflow? c. For the contents of registers $80 and $sl as specified above, what is the value of $to for the following assembly code? sub $t0,$s0, $s1 d. Is the result in $to the desired result, or has there been overflow? e. For the contents of registers $80 and $sl as specified above, what is the value of $to for the following assembly code? add $t0,$so, $s 1 add $t0,$t0,$s0 f. Is the result in $to the desired result, or has there been overflow
