Question 2:

a) Translate the following C code to MIPS. Assume f, g, h, i and j are assigned to registers $1, $2, $3, $4, $5

f = g + h; i = j - 3; j = j & 0xFFFE; g = h - j;

b) For the following two MIPS instructions, show the value of the opcode, rs rt rd and immediate fields as appropriate for that type of instruction (R- or I-type).

addi $7, $9, 4 add $18, $9, $0

c) Assume for the following instructions, variable A is assigned to register $18, B is assigned to $19, x is assigned to $7 and y is assigned to $9. Translate the three instructions into C code.

addi $7, $9, 4 add $18, $9, $0 add $19, $7, $18
