ALREADY GRADED A+
Operation of the microprocessor from Lab 4: - (ANSWER)fetch execute cycle: 1205
set to 01 for next step so it goes to the right next.
Use_pc = 1
Read = 1
load_ir = 1
How instructions and data are stored in memory: Under Opcodes
How different pieces of the microprocessor share the data bus: using a system of control signals on the
control bus to manage access and timing
How memory addressing works: Memory addresses are used to store and retrieve data, and to help the
computer manage memory.
AND A*B - (ANSWER)~(A AND B) = ~A OR ~B
OR A+B - (ANSWER)~(A OR B) = ~A AND ~B
NOT ~A - (ANSWER)~A
NAND ~(A*B) - (ANSWER)~(A AND B) = ~A OR ~B
NOR ~(A+B) - (ANSWER)~A AND ~B
XOR A ⨁ B - (ANSWER)~(A ⨁ B)
Boolean Functions - (ANSWER)A function that returns either true or false
How to represent a Boolean function in a truth table: - (ANSWER)Step 1: Label your variables on the top
row, and fill in with binary count going down

Step 2: Identify your equation and simplify it (use DeMorgan's rule if necessary, ie, (ab)' = a' + b' )
Step 3: Find which terms output 1 or 0 (if 1 combination is 1, then the entire row comes out to 1 if you
are using OR's)
How to represent a Boolean function in shorthand/algebraic form, including SOP and POS forms -
(ANSWER)Distributive rule: (a+b)(a+c) = a+bc
(x'+z')(x'+y+z) = (x'+z')(y+z)
Special case: (a+b)(a+b') = a+bb' = a
Associative rule: ((x'+z')+y')((x'+z')+y) = (x'+z')
POS: For odd number of terms w/same number of values: replicate
Minimize a Boolean function via Boolean algebra and also using K-maps - (ANSWER)a'b'c' + a'b'c + abc +
ab'c
a'b'(c' + c) + ac(b' + b)
a'b' + ac
See where the function becomes a 1 from last equation
