problem 7: (10 points) given this instruction sequence, 40hex sub $11, $2, $4 44hex and $12, $2, $5 48hex or $13, $2, $6 4chex add $1, $2, $1 50hex slt $15, $6, $7 54hex lw $16, 50($7) ... ... assume the instructions to be invoked on an exception begin like this: 80000180hex sw $26, 1000($0) 80000184hex sw $27, 1004($0) . . . show what happens in the pipeline if an overflow exception occurs in the add instruction. [hint: you need to discuss about possible detection of overflow, addresses which are forced into the pc, first instruction fetched on an exception, etc]
