Computer
Ever wanted to know how a computer works.If so the following steps will be helpful tosimulate a computer using SIMCO.
Step 1:Computer is made up of digital circuits.So it is best to learn about logic gates ,its truth table and its funtions.
Step 2: Design a logic circuit.
Step 3: Design a programmable logic design.
Step 4:
Digital Circuits:
Combinational circuit:
1.Basic gates:
AND
OR
NOT
EX-OR
NOR
NAND
2. Binary adder:
Half adder:
To add only two one bit numbers we go for half adder.
TT
A B S C
0 0 0 0
0 1 1 0
1 0 1 0
1 1 0 1
A & B -bits to be added
S-Sum[EXOR]
C-Count[AND]
Full Adder:
To add 2 or more bit numbers we use full addder.
TT
A B Cin Cout Sum
0 0 0 0 0
0 0 1 0 1
0 1 0 0 1
0 1 1 1 0
1 0 0 0 1
