Gut, kurz eine Rauchen, dann kommen, die schriftliche Dinger, auch Logarithmus berechnen, mit dem Taschenrechner
Heute kommt ausserdem auch - wie es jeden Tag sein muss
- Komplexes Schaltwerk - ASM-Diagramme - Kurzes MIPS Assembler Programm
1.) Rechne die Zahl in binaer Darstellung in eine Dezimale Darstellung um
0011110001011111b 15455d
2.) Rechne die Zahl in dezimal darstellung in eine Binaerdarstellung um
52699 1100110111011011
3.) Addiere die drei Zahlen schriftlich
26850
+ 21334
+ 34580
-----------------
82764
4.) Subtrahiere die letzten drei Zahlen schriftlich von der ersten schriftlich
17466
- 304
- 11055
- 5459
-----------------
648
5.) Rechne die Zahl ins zweier komplement um, mit 8 Bit - und subtrahiere diese zahl von der ersten und rechne das Ergebnis nach dezimal
-90 -45 = -135
10100110 11010011 = 01111001
6.) Multipliziere die zwei Zahlen schriftlich
53664*56775 = 3046773600
7.) Dividiere die zwei Zahlen schriftlich
6066/49217 = 0
8.) Errechne x Logarithmisch mit dem Taschenrechner

So, ich mache die Übrigen Aufgaben weiter. Zunächst die Zustandskodierung/Minimierung. Am Ende ein MIPS Programm. Ich denke, ich werde den Binomialkoeffizienten mit MIPS berechnen.

So, jetzt kurze Raucherpause, dann kommt das MIPS32 Assembler Programm.
So, jetzt kommt der MIPS. Zun"achst muss ich etwas tun, was ich schon immer mal tun wollte. Ich muss auf dem Taschenrechner Texas Instruments TI-30 nachgucken, wie geht der Binomialkoeffizient. Gut, wenn ich den habe, kann ich nach voll ziehen, ob MIPS das richtig ausgerechnet hat.

Es funktioniert generell schon mal, mit einem Problem - der mult Befehl tut nicht. Es geht, aber der mult Befehl tut nicht, also mal gucken
