Let us assume ALU’s overflow logic were broken for unsigned addition on your MIPS processor. We don’t want to buy a new processor. Could you solve this problem in software? Specifically, create a two real MIPS instruction sequence which places a 1 into register $t1 if the sum of $t2 and $t3 would cause a unsigned overflow and a 0 otherwise.

You could use the logic function for carry, it will give you when the sum overflows.
carry=number1 and number 2 (binary)
