Consider the MIPS code:

addi $$2,$$$0,0$

$L$: $lw$ $$3,0($$$8)$

$B1$: beg $$3,$$$16,L1$

$lw$ $$4,0($$$9)$

$sw$ $$4,8($$$8)$

sub $$5,$$$3,$$$4$

$lw$ $$7,4($$$8)$

$B2$: bne $$7,$$$17,L2$

addi $$2,$$$2,1$

$sw$ $$2,4($$$9)$

$L2$: addi $$3,$$$5,-1$

$sw$ $$3,0($$$8)$

$Iw$ $$6,8($$$9)$

$L1$: $lw$ $$9,12($$$9)$

$B3$: beg $$9,$$$0,L3$

sub $$16,$$$6,$$$16$

addi $$8,$$$8,12$

$B$: $jL$

$L3$: sub $$16,$$$16,$$$2$

$sw$ $$16,0($$$10)$

which is loaded into memory, with the first instruction at location $041008b00,$ to be executed in the

above DPU. Before running the code, assume that the $FC$ registers of interest contain the following values:

$$3$: $0$xffffffff

$$4$: $0$x$0$

$$5$: $0$x$0$f$7$a

$$6$: $0288$

$$7$: $01$

$$8$: $0$x$1003$ab$00$

$$9$: $0$x$10088$b$00$

$$10$: $0$x$1008$cb$00$

$$16$: $0$x$3$

$$17$: $0$x$0$

and the memory locations referenced by the code contain:

mem$[0$x$1003$ab$00]$: $0$x$1$

mem$[0$x$1008$cb$00]$: $0$x$0$DPU Show how the code is executed in the DPU of the image, as follows:

A$.$ Give the single timing diagram resulting from the run, based on the register and memory values listed

above.

B$.$ Provide all values generated within the DPU, either as data or control signals, separately for each

machine cycle, from the recall phase of the first instruction, to the result storage phase of the last

instruction.
