$5.....$Consider the following pseudo assembly code for

computing cab, Assume that a$,$ b$,$ and care assigned to consecutive memory "words" $($memory is generally addressed byte by byte and assume that a word s$4$ bytes$)$ and address for $"$a$"$ is $0$x$0000$ec$00.$ Also, we have a $=24,$ b $=110,$ and c $=20$ at the starting time. Assume that the first instruction of the code is stored in $0$x$00000128.$ Also, each instruction has the opcode in the first byte $($most significant byte$)$ and the remaining $3$ bytes specify the corresponding address. The opcode for store is $1,$ load is $2,$ and add is $3.$

$0$x$00006128$ load a

$0$x$0000612$c add b

Oxx$000$b $130$ store c

a$.$Show the memory addresses and contents for all the instructions and data involved. Use the format as follows to express your answer $($but the following is not the anower$).$ For all data, use hexadecimal representation.

Addresses contents

$01000021040$x$00000001$

$0$x$000021080$x$00000002(3+3=6$ marks$)$

b$.$ Write the micro instructions for the code segment Assume that current PC $($program counter$)$ is $0$x$0000$b$128.$ For each micro$-$instruction, also indicate the data that is transferred $($if it is a memory access$).$ For all data, use the hexadecimal representation. The following are the first two micro$-$instructions and the data transferred. Complete the rest
