README

This repository contains multiple small CPUs, simulated in Logisim.

Models

cpu8_v1

Extremely simple 8-bit CPU with 6 arithmetic (ADD, SUB) and logical (AND, OR, NAND, NOR) operations, conditional jumps are also supported.

The CPU has 6 Registers:

• 1x Constant loading
• 2x ALU operand
• 1x ALU result
• 2x General purpose

The program is read from a readonly memory (ROM).

Programming

In this repository I implemented a simple assembler, to make programming the CPUs easier. The assembler versions (branches) match with the CPU names.
