CPU AS A PROGRAM

⚙️ CAAP (CPU As A Program)

🧠 A simple virtual CPU that executes custom assembly-like instructions inside Python.

CAAP is a lightweight interpreter that simulates a basic CPU.
It lets you run simple text-based instructions like SET and MOV to manipulate variables, just like a minimal processor.

---

🚀 Features

• 🧠 Simple CPU-like instruction system
• ⚡ Fast and lightweight (pure Python)
• 📦 No external dependencies
• 🧪 Easy to extend with new commands
• 🎮 Great for learning interpreters and CPU concepts
• 👀 CAAP provides a low-level memory system to read and write external process memory using powerful pointer-based access.
• 🔥 It supports multi-backend control (ctypes & pymem), dynamic pointer chains, and future tools like scanners and value freezing.

---

📥 Installation

pip install caap

---

🧑‍💻 Basic Usage

from caap import cpu

cpu = cpu()
@cpu.scommand("SET")
def function(a,b):
    cpu.varb[a] = b
@cpu.scommand("MOV")
def func(a,b):
    cpu.varb[a] = cpu.varb[b]

code = """
SET A, 10
SET B, 20
MOV C, A
"""

result = cpu.run(code)

print(cpu.varb)

---

📊 Output

{'A': 10, 'B': 20, 'C': 10}

---

👨‍💻 pointers usage

from caap import cpu

cpu = cpu()

f = cpu.pointers("pymem")

game = f.Pointer("minecraft.exe")

game.set_value("health123",value=999999,type="int")

print(game.get_value("health123"))

---

📊 Output

999999

🚀 Version 0.0.5 ( latest )

✨ Added

• Added external process memory modification support (read/write to other applications)
• Added ctypes backend address auto-normalization (string → hex int)
• backends for external process memory modification ( pymem , ctypes )
• Improved memory write stability with pointer handling
• Better error handling for invalid memory addresses
• Added support for stable pointer-chain resolution, allowing memory values to stay accurate even after restarting the target program.

🛠️ Fixed

• Fixed crash when passing hex string addresses (e.g. "00D6FCDC")
• Fixed ctypes pointer conversion errors in write operations

⚡ Improved

• More stable memory backend behavior
• Cleaner internal address processing pipeline
• Reduced user-side input restrictions for addresses

⚙️ Supported Instructions

Instruction	Description
SET A, value	Assign a value to a variable
MOV A, B	Copy value from variable B into A

---

🧠 How It Works

CAAP reads each line of text, splits it into commands, and executes it using an internal memory system (like CPU registers).

Each variable acts like a register inside a virtual CPU.

---

🔥 More Examples

📌 Example 1: Simple Math Storage

SET X, 5
SET Y, 15
MOV Z, X

Output:

{'X': 5, 'Y': 15, 'Z': 5}

---

📌 Example 2: Overwriting Values

SET A, 100
SET B, 50
MOV A, B

Output:

{'A': 50, 'B': 50}
