\section{Teilaufgabe1: Messen von $f_{hsync}$ und $f_{vsync}$ }
Bei dieser Teilaufgabe mussten wir horizontale Synchronisationsfrequenz $f_{hsync}$ und die vertikale Synchronisationsfrequenz $f_{vsync}$ mittels geeignete Modi bestimmem. Dabei war gegeben, dass $f_{hsync}$ per Timing-Mode und $f_{vsync}$ per State-Mode gemessen wird.

\subsection{$f_{hsync} = 29.458\mu s = 33946.64 Hz$}

\section{Teilaufgabe2: Farbe des Pixels (317,148)}
Hier war die Farbe des Pixels (317,148) per State-Mode darzustellen. Dabei benutzten wir einfach die Signale LINCNT und COLCNT und setzten diese auf entsprechende Werte. Der Pixel hat die Farbe (0,0,1).

\section{Teilaufgabe3: Hintergrund und Objektkante}
Zuerst war die Hintergrundsfarbe zu bestimmen. Da wir bei der vorigen Aufgabe den x und y Teil der Koordinaten vertauschten, hatten wir diese Farbe schon bestimmt, weil sich dieser Punkt offensichtlich in keiner der Objekte befindet. Wie aus den Screenshots ersichtlich, handelt es sich um die Farbe (1,0,1).

Um nun die x-Koordinate der linken Kante des linken Objektes zu bestimmen, beginnen wir ab den Koordinaten (0,0) zu ``suchen'' und triggern auf die die Farbe (1,0,0), da dieses Objekt offensichtlich Rot ist)

F\"ur beide Aufgaben benutzten wir den State-Mode. (WARUM???)

\section{Teilaufgabe4: Hsync-FSM}
Hier verwendeten wir die selben Triggerbedingungen wie in Teilaufgabe1 fuer $f_{hsync}$. Die FSM ist in den folgenden Abbildungen ersichtlich.

???? Die States PRE\_B und PRE\_D sind aufgrund ihrer kurzen Dauer nicht (deutlich) in den Abbildungen ersichtlich (vgl. Tabelle 1.4 im Skriptum).
