Question

For each MIPS instruction, show the value of the opcode (OP), source register (RS), and target register (RT) fi elds. For the I-type instructions, show the value of the immediate fi eld, and for the R-type instructions, show the value of the destination register (RD) fi eld

Answer 1

For each MIPS instruction, show the value of the opcode (OP), source register (RS), and target register (RT) fi elds. For the I-type instructions, show the value of the immediate fi eld, and for the R-type instructions, show the value of the destination register (RD) field

Explanation:

\begin{fancyquotes}

 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.
