Consider a LEGv$8$ Datapath, where registers X$6,$ X$7,$ and X$8$ are initialized to $6,7,$ and $8$ respectively. Other registers are initially zero $(0).$ Then the following LEGv$8$ code segment is executed.

ADD X$6,$ X$7,$ X$8//$Instruction $1($I$1)$

SUB X$10,$ X$7,$ X$6//$ Instruction $2($I$2)$

SUB X$11,$ X$10,$ X$8//$Instruction $3($I$3)$

Identify if there are any data hazards. Name a technique and briefly explain the technique to avoid the data hazards $($if any$)$
