Searched Projects

I finally did it.
I made my own 8-bit CPU! With a bit of inspiration from other CircuitVerse projects and from a book called, Digital Computer Electronics.
The premade program does this: 12 + 6 - 3 + 2 (which equals 17)

program the computer by typing in the opcodes in the ROM

Opcodes: (X = address)
0X = Load X's value to Accumulator
1X = Add X's value to Accumulator
2x = Subtract X's value from Accumulator
ee = Take Accumulator's value and put it in the Output
ff = Halt/stop everything

Versions (Date format: DD/MM)
9/11 v1.0 - Finally finished it!

A simple 8-bit full adder / substractor.

S will compute the result of A + B or A - B

Use 7 bit numbers in subtraction mode (at least for B, to prevent an overflow).

This is a WIP, I am doing this because I have a new computer and I need to branch it to continue, however I will still be using this during school so I will swap between them

Its elementary.

An 8 Bit Computer

USE ON A COMPUTER

Same as V2 exempt that there is a Jump if zero command

JO: Jumps if the ALU output is 0

And you can under stand things better!

(these instructions arent done)

A collection of binary adders with Binary, Hex, and Decimal input and output representation

A simple 8-bit arithmetic logical unit.

The following commands are implemented:

Logic Operations:
[0] 000: OR
[1] 001: NAND
[2] 010:NOR
[3] 011: AND
Arithmetic Operations:
[4] 100: ADD
[5] 101: SUB

The two's complement for subtraction is implemented with a NOT Gate and an adder (which simply adds 1 to the negated input).
