Question $1$:

Consider that the machine has the following state of memory for questions $($a$)$ and $($b$)$ below. Please note that each row corresponds to one byte of memory. For each question make sure to pay attention to the endianness of the system.

$\begin{array}{cc}\text{M}\text{e}\text{m}\text{o}\text{r}\text{y}\text{A}\text{d}\text{d}\text{r}\text{e}\text{s}\text{s}& \text{M}\text{e}\text{m}\text{o}\text{r}\text{y}\text{C}\text{o}\text{n}\text{t}\text{e}\text{n}\text{t}\text{s}\\ 0BBBB0000& 072(rin\text{A}\text{S}\text{C}\text{I}\text{I})\\ 0xBBBB0001& 061(ain\text{A}\text{S}\text{C}\text{I}\text{I})\\ 0xBBBB0002& 074(tin\text{A}\text{S}\text{C}\text{I}\text{I})\\ 0xBBBB0003& 073(sin\text{A}\text{S}\text{C}\text{I}\text{I})\\ 0xBBBB0004& 000\\ 0xBBBB0005& 000\\ 0xBBBB0006& 000\\ 0BBBB0007& 000\end{array}$

a$)$ Consider that register $ to holds the address $0BBBB0000$ and $ t$1$ holds $066726f67.$

What will the following memory locations look like after executing: sw $$t1,4($$$t0),$ assuming your system uses BIG endian. Show in the table using HEX values.

$\begin{array}{cc}\text{M}\text{e}\text{m}\text{o}\text{r}\text{y}\text{A}\text{d}\text{d}\text{r}\text{e}\text{s}\text{s}& \text{M}\text{e}\text{m}\text{o}\text{r}\text{y}\text{C}\text{o}\text{n}\text{t}\text{e}\text{n}\text{t}\text{s}\\ 0xBBBB0004& ?\\ 0xBBBB0005& ?\\ 0xBBBB0006& ?\\ 0xBBBB0007& ?\end{array}$
