Detector de circuito de erro em código BCD com o acionamento de uma lâmpada( Sinal Alto).

Just wanted to make something cool for a FIRST PROJECT and decided on a lock.

The goal is to get the light on by finding the right code using the gates.

New and improved JCU 501! The new JCU 501 contains two accumulators (one for each input), as well as capacity to handle it's own input stream.

You can either use the ROM or the RAM to program it 

Functions:

0 - A OR B        /  0000

1 - A AND B     /   0001

2 - A XOR B    /    0010

3 - A + B           /    0011

4 - A NOR B    /    0100

5 - A NAND B /    0101

6 - A XNOR B /    0110

7 - !(A + B)      /     0111

8 - A = B         /      1000

9 - A > B        /       1001

a - A < B        /       1010

b - 0               /       1011

c - A != B       /        1100

d - A <= B     /         1101

e - A >= Bf - 1 /       1110

Addresses:

0 - 0000

1 - 0001

2 - 0010

3 - 0011

4 - 0100

5 - 0101

6 - 0110

7 - 0111

8 - 1000

9 - 1001

a - 1010

b - 1011

c -  1100

d -  1101

e -  1110

f  -  1111

This is My 4 Bit computer with 6 instructions just like the SAP Computer. :)

Instructions:

00 NOP

1x LDA

2x ADD

3x SUB

ee OUT

4x OUT_S

ff END

Warning:

This computer cannot calculate more than 2 numbers

This Example Program shows 5+7 and 4-5.

To Program, Set the Reset Bit to 1 and Program the ROM.

To Run the Program, Set the Reset Bit to 0.

The Numbers in the output are in Two's Complement so if the number is more than 7 

than the number will be negative because 7 is the biggest number in 4 bits.

Example code (in Binary):

0000000001101000

0000000001101010

0000000000000001

Example code (in HEX):

0x68

0x6a

0x01

Example code (in asm):

SAVE 1101 R1

OUT R1

RST R1

Example code (explanation):

Saves "1101" in register 1

Outputs what's in register 1

Resets register 1

I'll add more instructions, functions and features in the future
