Make any additions or changes to the datapath which are needed in order to make the RTLs for the instructions possible. The base datapath should be in black, with changes marked in red and other colors $($one color per new instruction$).$

New Instructions:

New: $$bcon$,$xnori$$

bcon $($Branch if consecutive$)$: This I$-$type instruction branches to the target address only if RF$[$rt$]$ has the value of a consecutive address value held in RF$[$rs$]($When the value in RF$[$rt$]$ is RF$[$rs$]+4,$ and word$-$ aligned, i$.$e$.,$ divisible by $4).$ Otherwise, the branch is not taken. Usage: bcon rs$,$ rt$,$ label. Example: bcon $a$1,$ $a$0,$ loopStart $($when $a$1$ is $8$ and $a$0$ is $12,$ the branch is taken$).$

xnori: This I$-$type instruction zero$-$extends the given immediate then bitwise XNORs it with RF$[$rs$]($XNOR is the complement of the XOR operation, returns $1$ if either both bits are zero or both bits are one$)$

The result is written into RF$[$rt$].$ Example: xori $t$0,$ $t$1,0$x$0040.$
