Consider the execution of a simple sequence of statements:

$S1$: $x=Y+C$

$S2$: $x=10+C$

$S3$: $B=E^{**}10$

$S4$: $A=x+B$

Q$1.$ Identify the set of data dependencies. We must indicate the type of each data

dependency

Q$2.$ Draw the Data Dependency Graph $($DDG$)$

Q$3.$ Propose a solution to enhance the parallel processing. Think about the dependency

between S$2$ and S$3$
