CPU-Simulator

Python program to simulate CPU functionalities using OOP structure.

Structure

📁inputs - Modifiable input files to be read into simulation
| data_input - Contains sample data that are read into memory bus
| instruction input - Contains sample instructions that are read into CPU

cache.py - Cache class
cpu.py - CPU class that contains the bulk of the applicable programming. Utilizes intstantiations of the cache and memory bus
main.py - Instantiates CPU, reads applicable data, and runs the simulation
memory.py - Memory bus class

Instruction Key

Command	Argument	Function
CACHE	0	Turn cache off
CACHE	1	Turn cache on
CACHE	2	Flush cache
JMP	INT	Jump to specified position
ADD	Destination, Source, Target	Add target and source register values on destination register
ADDI	Destination, Source, Immediate	Add immediate value to source register on destination register
HALT		Halt program
