Project #1 Exploring Multiple Processes and IPC

Project Description:

This project simulates a simple computer system with a CPU and Memory. The CPU and Memory are implemented as separate processes that communicate using pipes. The CPU executes a user program stored in memory. The user program is written in a custom assembly-like language and consists of a series of instructions. The CPU has registers (PC, SP, IR, AC, X, Y) and supports various instructions for arithmetic, memory operations, I/O, and control flow.

My File Description:

1. CPU.cpp - Contains the implementation of the CPU functionality, including instruction execution and interrupt handling.
2. CPU.h - Contains function declarations and constants used in CPU operations.
3. Memory.cpp - Implements the memory functionality, including loading a program from a file and handling memory operations. Coordinates the execution of the CPU and Memory processes, sets up pipes for communication, and manages the overall program flow.
4. Memory.h - Contains function declarations for memory operations.

How to Compile:

g++ CPU.cpp Memory.cpp -o p1

Note: p1 is the name of my executable file.

How to Run:

./p1 sample1.txt 30 ./p1 sample2.txt 30 ./p1 sample3.txt 30 ./p1 sample4.txt 30 ./p1 sample5.txt 30
