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     1       0          1
0   1     0       0          1
0   1     1       1          0
1   0     0       0          1
1    0     1       1          0
1    1     0       1          0
