$(32$ points totally$)$ The following tables represent a small piece of memory, PC$,$ IR$,$

and the eight general purpose registers of LC$-3.$ In these tables, the memory

addresses are represented in hexadecimal format, and the memory contents, PC

content, IR content, and the contents of the general purpose registers are

represented in binary format. Refer to these tables for the following questions.

a$.(8$ points$)$ Which of the registers $($including the general purpose registers $R0$

$$ R$7$ and the special purpose registers PC and IR$)$ are modified during the

first instruction cycle? What are their updated binary values, respectively?

b$.(8$ points$)$ Which of the registers $($including the general purpose registers R$0$

$$ R$7$ and the special purpose registers PC and IR$)$ are modified during the

second instruction cycle? What are their updated binary values,

respectively?

c$.(8$ points$)$ Which of the registers $($including the general purpose registers R$0$

$$ R$7$ and the special purpose registers PC and IR$)$ are modified during the

third instruction cycle? What are their updated binary values, respectively?

d$.(8$ points$)$ Which of the registers $($including the general purpose registers R$0$

$$ R$7$ and the special purpose registers PC and IR$)$ are modified during the

fourth instruction cycle? What are their updated binary values, respectively?
