+\mytitle{Assembly, at Last!}{\co}
+
+After a long wait, we finally got to assembly. We began using a simple
+assembly-like language called MARIE\footnote{\url{https://marie.js.org/}} which
+is implemented as an online simulator, allowing us to write and run our projects
+and having simple debugging tools at our disposal.
+
+Being the first homework, the assignment didn't consist of too many questions
+complex questions, but just enough to get us started.
+
+Questions included introspection of the memory addresses, to figure out the
+addresses and values of registers and memory locations. Additionally, we had to
+write a simple program that would take two numbers from the user and multiply
+them both by three. Since multiplication is not a built-in operation in MARIE,
+we had to implement it using addition. Given that the multiplicand is a
+constant, three, we could simply add the multiplicand to itself twice, for each
+of the input numbers.
+
+\begin{lstlisting}[language=Ant]
+  Load  a / AC =  a (2)
+  Add   a / AC = AC (2) + a (2)
+  Add   a / AC = AC (4) + a (2)
+  Store a /  a = AC (6)
+
+  Halt
+
+  a, DEC 2 / a = 2
+\end{lstlisting}
+
+That's the basics, but of course we had to implement input and output as well,
+which wasn't all that much, just a few extra instructions.
+
+Following that portion was a set of problems which had us answering what
+hexadecimal opcodes would be generated for a given MARIE instruction, but
+backwards, so which instruction would be generated for a given opcode. This was
+a good exercise to get us familiar with the opcodes and their corresponding
+instructions. Additionally, we dealt with a few theoretical problems such as
+given a IR (instruction register) and the offsets for the opcode and operand
+fields, what we would be able to accomplish with that information. The questions
+included things such as the number of opcodes possible, the number of
+addressable addresses, the most negative decimal number that would be
+represented, and so on.
+
+Finally, we had to write a program which would take two numbers from the user,
+and just swap them around. Similar to how you would implement this in C, we had
+to use a temporary variable to store one of the numbers while we overwrite it
+with the other number.
+
+\begin{lstlisting}[language=Ant]
+  / t = a
+  Load  a
+  Store t
+
+  / a = b
+  Load  b
+  Store a
+
+  / b = t
+  Load  t
+  Store b
+
+  Halt
+
+  a, DEC 1 / a = 1
+  b, DEC 2 / b = 2
+  t, DEC 0 / t = 0
+\end{lstlisting}
+
+We had to implement input and output here as well, but you get the idea.
+
+The quiz for this week was nearly identically to the homework, save for the
+programming portion which was worth 40 points compared to the usual 4 or 8. The
+question was similar to the homeworks, except we had to add a portion that
+calculated the sum of the two numbers.
